Reminds me of my favorite crypto joke: "cryptocurrency is an alternate banking system for people whose primary complaint about the 2008 financial crisis was that they weren't _in_ on it."
It is very hard to get approval to be a bank and they are highly regulated. Many in crypto liked the idea of being able to run a bank out of their bedroom similar to any other SaaS business. Like many jokes, a truth told sideways can be quite funny.
The primary complaint about the 2008 (and the entire move to fiat) is (1) the government gets to print money at its own whim, deflating everyone's hard work. (2) fiat is inherently based on usury, which billions of people find appalling and abhorrent. What happened in 2008 was the natural outcome of such a system, and it will continue to happen if things are not fixed.
It's hard to find a successful pyramid scheme or bubble that I'm not upset I wasn't on the ground floor of. I'm also upset that I didn't win the lottery. It doesn't mean that I secretly think pyramid schemes, lotteries, and beanie babies are good, and that I'm naysaying them because I didn't get a piece. I would naysay them 10x as much if they had made me rich. I'd be rich and an authoritative source, who's going to stop me from talking shit about the things I dislike?
