No, it's exactly why that works.

Criminals used to meet in person to discuss crime (because mail/phones can be intercepted) and meet in person to move cash. It was a hard limiting factor on what they can get away with. With e2e messengers and anonymous crypto both of those "issues" are fixed.

Do you know anyone who uses it for legit purposes? I don't. I bet you ban a coin like that and you kill orders of magnitude more crime revenue compared to .001% of honest users using it to send money home and save a few dollars on the transaction.
