There's a big difference between the average American incidentally violating felony statutes in the course of every day life, and the cryptocurrency situation where it's never really a question of whether they are intentionally committing crimes. There's questions of which crimes, how big, and whose funds get lost/stolen...but there's always crimes.

A lot of why there are crimes is that crypto is inherently global but there two hundred or so different countries out there making ever changing and vague laws so allowing someone to exchange one token with another one will probably violate some regulation in some country.

No need to go that far. Crypto main selling point is anonymity. There is not significant bitcoin exchanges out there which is not processing crime money and I mean actual crime: extortion, drug trafficking, human exploitation and let’s not even talk about fraud. There is no need to whitewash them.

Which is generally not true anyway, same as lots of sayings.
