OFAC already sanctions crypto wallets. https://ofac.treasury.gov/faqs/594
replyYou can't track individual coins, so you'd have to "taint" entire wallets. Using a mixer would taint the mixer and every wallet it sent to. I'd think this would end up tainting almost everything before too long.
replyBitcoin also doesn't require the receiver to authorize a transaction, so if you had control of a tainted wallet, you could taint other wallets at will, wielding it like a weapon.
Doesn't seem feasible. Not that this always stops legislators.

replyIs that actually an issue? I am looking for it but I can't see a downside.
It was at least in theory an issue when they tried to sanction mixers. In fact people would purposely send tainted crypto to well known wallet addresses of celebrities etc. making them technically run afoul of OFAC
replyDepends on your goal. If you want to keep the system going while blocking "dirty" money, it's not going to work. If you want to use that as a stealth method of banning the whole system, then full steam ahead.
replyWould banning the whole system have any downside? It's still unclear to me what crypto is supposed to be useful for.
