Thoughts on all this endless legislation?

We've all been expecting this for years now. As crypto gains popularity and looks like it will one day threaten the dollar, here come the government and bankster scumbags to try and stop it. Good thing crypto is designed to resist all this. It looks to me like they can pass all the laws they want, and have all the little meetings they want, and there's nothing they'll ever do to stop the advance of Defi.

Except for one little thing, which they haven't done yet, but may eventually: They could make the banks turn off any dealings with crypto exchanges. Of any kind. If they won't let people leave bitcoin and get back into the dollar, well, that kind of squashes the rest of the adoption we need to fully push the dollar into the background. And have bitcoin finally become the world's most used currency. (or some other real crypto but my guess is it would be bitcoin as it's the most popular)

What if they do that? What if they pretty much outlaw bank transfers of any kind when it comes to crypto? Can't buy, can't sell. Can't sell a bitcoin and go get you a new car. Can't sell several and pay off your house and live debt free. Now you just have a nice internet money, that you can't ever exchange for dollars when need be. What do we do then?
