That is a straw man. This is not my definition of crime, I was thinking things like money laundering, tax evasion, ransomware payments, and blackmarket purchases.

I'm genuinely not sure what a use case for unregulated financial activity would be that doesn't fall into those buckets.

Someone mentioned retaining assets in countries with hyperinflation. To me it appears a central bank digital currency would be more appropriate there.

A straw man? I just wanted a definition of "crime".

"Blackmarket purchases" has the same problem "crime" does, it's self supporting.
