Please name a use for crypto which is not "buying questionable substances from the internet" or "like stocks, except that I can make more of them with my GPU".
They are, in every way, of less value to the economy than traditional fiat currency.
* They have no guarantees or equivalent to the FDIC
* Their value similarly unpinned to anything (for the sake of argument, let's ignore basketed currency, since crypto is not comparble to that and less table than those) other than investor confidence like FOREX
* They are not tax havens
* Their "production" consumes as much energy as some medium-sized nation-states
* Chasing the hype has exacerbated the chip shortage as "peak capitalism" has encouraged fabs to produce GPUs for maximize profits at the expense of, say, chips for cars with their limited supplies
Not everyone who uses crypto is a dark hat crypto-libertarian hacker. Few people who clamor for crypto have good reasons to use it other than "why not have it as an option for people who want it?" or "I wanna do this stuff without being tracked".
