That’s not my argument. Crime is not gone, tools are changing and the enforcers are trying to catch up.

Cash is now for petty criminals only. For anything beyond car level of money you need involvement of politicians or high end criminals.

They tend to use gold and fake bank transactions BTW.

Just today there is a trial of the Turkish bank Halk Bank that was allegedly caught laundering money for Iran. High ranking Turkish and Iranian politicians are involved, the funds in form of gold were transferred using private jets and laundered through Dubai. The defense of the person who run the gold operations includes Rudy Giuliani. The things are at that level now.
