> holding 100s of millions or billions of other people's money, that's enough to hit screw-it money in a few years without the constant fear of things going terribly wrong.

so, you can have that honest 2% per year for several years or you can just take it all almost immediately. History as well as crypto today is pretty clear about what humans prefer. Absent the "take it all immediately" option people do though go for the 2% option. So if you see that they can go for such an option and yet haven't - i.e. they think they have a much better option than to earn easy 2% off somebody's billions (what can be better than that?) - that is a clear sign what option they really chose :)
