yeah, the one thing that makes me think this was the work of one person is the fact that a group, even a close knit group of NSA/CIA/GCHQ operatives could not produce, test and release something liek this without one of them making an error. I assume that satoshi thought through the production and release of this software well in advance of actually doing it, i.e. never suggesting it on a forum account, never testing or discussing it with anyone until he was soewhat ready to go. However his posting to the cypherpunks group does make me think he was at least a lurker on there before he signed in as satoshi, hence his decent OpSec.
The gateway monitoring argument is also pretty feeble since how are they going to extract ID scans or other info from worldwide gateways or p2p sales. Sure bitcoin is risky if using a major exchange in a western country but good luck getting info on a trade from a Russian exchange, or IRC exchanger connected via Tor who lives in Vietnam
