I didn't see any calculation in the parent comment.
The point of my original comment was to point out a couple of things we'd have to include in a cost/benefit analysis of KYC/AML regulation, not to actually do a proper analysis, which I would expect to run to hundreds of carefully researched pages.
It also flatly contradicts the fact that the US didn’t lose 16% of its GDP to mafia activity before KYC laws were introduced.
