You don't even need to off-ramp it, which was the whole point of crypto.

I could cut your lawn, sell you an Xbox, or buy an old tractor completely with BTC. The government can cry about it all it wants, it can pass a hundred laws, or issue a thousand court orders.

We've already seen this play out with the illegal drugs trade and P2P file sharing. Spoiler alert: The government lost.
