If I understand you, you are saying that Ethereum is not important because people are not valuing as highly as BTC, so the transaction throughput is irrelevant and L2 is not going to be needed.
This is akin to saying that it doesn't matter that e.g Brazil has a more advanced banking retail industry compared to the arcane networks from the US because the Brazilian economy is not as big as the US.
This is silly, because not only the two economies can co-exist, there is no technical aspects that stops other chains to adopt PoS as well it also ignores that the value can be migrated from one chain to another.
Increasing throughput in Ethereum would make everything more valuable. Just as an example, people can get their BTC and transform wrap them to use in the ethereum chain. With ETH2, it will be cheaper to wrap BTC and cheaper to use it in transactions.Its utility will be increased.
Also, I said that there are many things yet in the way to facilitate adoption, no need to move the goal-posts.
