shit like "muh wealth inequality", nevermind that wealth inequality explodes in the US every time they turn on the money printers.
shit like "muh environment" when Bitcoin's energy usage is trivial and puts hard restraint on insanely destructive (and environmentally unfriendly!) things like, y'know, global empire.
"nobody actually uses crypto" isn't leftist exclusive but it's equally dumb, gresham's law dummies. Plus, saving in a hard money is using it.
"Fix the money, fix the world" is a bit messianic but it's pretty fucking true. Fiat money is at minimum exacerbating every significant societal ill I can think of, and in many cases, they wouldn't exist at all without fiat.
