“Impossible” might be an exaggeration, but it does seem to make it much easier.
It’s not harder to stop, it’s easier—blockchain is far easier to trace than cash, which is what is used now. And I’m skeptical for both of those reasons.
They can also use chain-analysis and put pressure on mining groups within their countries to do KYC/AMF or to create address “black lists” but so far there hasn’t been much political will for this
NatSec people already have large groups working on this, and my understanding is that even the best BTC wallets and mixers aren’t actually much help. And despite limited political will, OFAC has added people and addresses, and as far as I’m aware, no one has successfully moved money out of any of the (very few) OFAC-blocked addresses. Maybe that’s not pools enforcing the rules, and obviously blocking individual addresses is incredibly naïve as a strategy, but I will note that pools and other key players have every reason not to want to piss off the US Government.
