if there's a will there's a way. Just look at projects like bisq and fiatdex. Not to mention the pretty obvious solution of just using crypto as money.
Also, things like I mentioned definitely still work.
You said these things were easy. My point is that it will be increasingly difficult to do so. Your comment about "If there's a will there may be a way" is not the answer because having a "way" doesn't mean it's easy, and that was exactly my point. Tor exists, but that doesn't mean it's easy to do Tor, nor do regular people use Tor.
