I guess the solution is to create a shell company for your illegal activities?
IMO part of the reason the SV tech bros are embracing right wing grift culture so publicly now is that this method, which had been serving them well for decades, doesn't really work without the infinite free money lending spigot being wide open.
By the time the cheque comes, your illicit venture either went bust or you built a bilion dollar empire capable of buying the best lawyers and lobbying to walk away clean.
