> Obviously, a day will come when the biggest processors (ie Coinbase) will be forced to not accept certain clients / transactions, effectively destroying in practice the possibility of exchanging cryptocurrencies with dollars. This would only prevent that possibility for the affected clients and only on Coinbase. By the way Coinbase already has the possibility to blacklist any USDC address it is required to do so by law enforcement. (USDC being a stable coins basically worth 1:1 with USD at this point). And that is because the smart contract governing USDC can have its list of blacklisted addresses updated at any moment. So in a way the day you're talking about is already there.

But there's a difference between "being required to do so by law enforcement" and "doing it preemptively". And obviously, there are many exchanges other than Coinbase. The point is, I'm not even a crypto fan, but everytime someone comes up with the "how are crypto useful?" question, I can't help thinking "at the moment, they're the only alternative to VISA / MC for payments".
