I think there are a very small number of people who were interested in crypto from the get-go for what I'd consider good, socially positive reasons. To the extent that those people didn't cash in and are mad about how it turned out, I respect their pain. It's always hard to watch the beautiful dream get corrupted. It would have been a very interesting alternate timeline if those few pure souls were left to innovate quietly on their own for a couple of decades.
But as far as I can tell, the rest of it is at best, IGMFY [1], and at worst just scams. And that's the great, great bulk of it. I get why crypto adherents are going through a there-must-be-a-pony-in-there-somewhere [2] stage. But I would like to suggest that there is in fact no pony. That 99+% of the "crypto community" is composed of suckers, people in on the grift, and people who are simultaneously both.
And I'd also like to suggest that things like FTX are not outliers. They are the absolutely predictable outcome of people saying, "What if we make an end-run around the financial regulatory apparatus and ignore all of the history that drove its creation?" I understand that the anarchocapitalist fantasy is that if we just end government we'll all live in Shangri-La. But the reality of is the sort of warlord despotism you seen in failed states. (Which, as an aside, has given us another meaning for "techincal". [3])
Similarly, the real-world version of financial anarchocapitalism is bubbles, fraud, crime, and grift driving out actual development and investment. That's why every successful marketplace in the world above the size of a street market has significant regulation, be it internal or external. I used to write financial trading software. The people who I worked for were dispositionally cowboys. But every one of them knew that you did not fuck with the exchange and the clearing firm. And maybe the national regulator, but that was a distant concern compared with the people who were running the marketplace and would happily clip your wings if you looked at all like you were pulling something.
