I hope you do not seriously believe that the reason gold is not used for trade is that governments suppress it. The fact is that using gold is actually extremely impractical compared to modern forms of payment.

The use of gold in trade in the past developed naturally because sufficiently stable fiat money systems did not exist. However, once such fiat money systems do exist, they are simply better and there is no reason left to use gold as a medium of exchange (outside of goldbugdom).

As to gold being impractical for use in everyday transactions, I don't think that's true anymore. You can look at companies like Goldmoney for a real world example of what is possible. Any trusted third party can hold the physical gold, while allowing electronic transactions of said gold in whatever increments, without any physical exchange taking place. In fact, this is generally how the dollar worked before it went off the gold standard.

I'm not sure why you think fiat money is better. The history of fiat money has been one of short lifespans and dramatic failures, while gold's history of use as money spans over 6,000 years.

Would it? Gold has gone up nearly an order of magnitude in a decade. Has this caused your computers cost to go up dramatically? Are there industrial alternatives to gold? Would stability of the value of your currency be worth an increase in the cost of consumer electronics?

I know no right thinking person, especially with an elite education, would consider a gold standard.

All the more reason to consider it carefully.

However, if you know that there are about 140,000 tons of gold in existence and somewhere around $9(M2) trillion in US money supply in existence, you do the math on how much gold would be worth.

The main point of my post was that this is such an obvious point that is not addressed, meaning that even the idea of moving to a gold standard is not well-thought out. Poor analysis is enough for me to dismiss the idea without a second thought -- only idiots play roulette with a nation's entire money supply.

I'm being a bit hyperbolic, but $2000 gold is around the corner, and the bottom in the early 2000's was well under $400, depending on the market you look at. The move in gold has been hyperbolic. Have you seen that pass through to consumer electronics? Are there alternatives to gold for these industrial uses?

I agree entirely that only idiots play roulette with the nations's entire money supply, which is precisely why we should take the roulette wheel out of the hands of the money printers at the privately owned Federal Reserve.

As to the question of what is better, my answer to that is two-fold.

First of all, history paints a misleading picture of the strength of gold-backed currencies. After all, when things go seriously wrong economically under gold-backed currencies, ending convertibility is usually one of the first things that governments do. Then the final death of the currency happens after it has become a fiat currency, but of course the failure is ultimately one of a gold-backed currency. Generally, whether a currency fails is not related to whether it is fiat or gold-backed anyway (such as with the failure of the Weimar mark, which happened to be fiat money; but both the move away from gold convertibility and the hyperinflation were caused by the First World War).

Second, while it is obvious that fiat money can be rejected totally, and gold will always retain at least some minimum value based on its use in jewellery and industrial production, this is not a useful measure to decide which system is better.

I claim that the real measure should be: How well does the economy fare, how well does it serve society, under a modern fiat money system vs. older systems.

Here, there is a great amount of evidence in favour of modern fiat money arrangements. Compare the cycle of booms and busts in the 19th century with the relative calm of the second half of the 20th century. In fact, that period was so calm that economists even claimed that the business cycle had been tamed! (They called it the Great Moderation.) Of course, this was hubris as the current crisis has demonstrated, but it should give you a taste of just how successful the combination of modern central banking with fiat money has been.

(I do not think this calmness was purely due to using fiat money, but I would claim that using fiat money certainly helped. The correlation is obvious, one can debate over the causal link of course.)

How is that inherently better than fiat money? You are essentially trusting that the government will provide you with the gold on demand. The government could overprint & not actually have enough in reserves to cover all gold requests.

Additionally silver/gold certificates were redeemable for silver or gold dollars. The world gold market started making these coins worth more than the face value. You started to get speculators who would cash in & then sell the gold for more than the currency was worth. This also happened to Britain with their gold standard. Not to mention the overhead required to maintain & store large volumes of gold as well as punching out expensive gold coins.

I can see the nice concept of having a currency independent of government, but when you boil it down, money is all about trust. Even if we were on a world gold standard we would have to have faith that gold will keep a stable value & that other players in the market are being truthful about their reserves.

About the US tax system, which I don't know too well: what about exchange of foreign currencies? Are they subject to capital gains or some other form of tax? Does the capital gains tax actually apply if you use gold for payment, and not just if you sell the gold in exchange for US$?

Most people are willing to pay a few cents on the dollar (whether that rears its head as actual risk of theft, risk of default or risk of inflation, or as insurance against those possibilities) in order to be able to trade things with other people.

The modern economy is very good about keeping its costs stable and low, while steadily increasing the speed and ease with which we complete transactions. I'd say that's a pretty good thing.

Let's take a very simple example. Say there are two people on an island. The first can build boats, the latter can fish. There is no currency. What should happen?

Case 1: No transaction. Both die. Case 2: The first builds a boat (boats are very resource intensive!) and gives it to the second. The second fishes and has fish. The first dies because he has no fish. Case 3: The first agrees to build a boat and rent it to the second in return for part of the first's weekly catch for the next 10 years.

To support Case 3, you basically need contract law. But the contract in question is very inflexible. Does the boat maker enter into similar contracts to cover his needs for clothes, etc? Ideally the boat maker could just sell the fisherman the boat and use the money to buy fish or clothes or anything. So you need currency.

The key question is: how much currency do you need?

Obviously, you need enough to be able to serve as a proxy for the goods and services in your economy and promises thereof. The Fed may not be great at estimating that amount, but pegging it at how quickly you can mine gold out of the ground doesn't make any sense either.

Would new entrants in the market attempt to find more efficient ways to extract gold?

Would alternatives to gold as a currency arise?

I'm not convinced that a gold standard would be perfect. I am quite convinced that the current private exponential issuance of debt-based fiat currency by a money printing madman is insane.

I really don't know. I just don't think that our academic betters know either, despite their pretenses. I tend to think that any idea that our friends in economics dismiss is worth considering carefully, given how wrong they've been in the last decade plus.

The U.S. grew at its fastest rate under a hard money gold standard, with heavily restricted immigration and almost no government, financed with tariffs, of all things. Does that mean we should adopt those policies? I dunno man. I do know we were industrializing at the time and, hey, look at that, there was a literally unbelievable explosion of goods, services and promises thereof.

So I try to keep an open mind on this stuff.
