I suspect the argument is more the particular KYC required by American law, eg, as long as your bank can identify you as a particular customer, they shouldn’t be required to collect certain information by law.

Though if I were going to rant, it would be about how constructive surveillance, such as requiring banks keep certain records and then claiming those records aren’t protected from search because they’re third party business records and not those of a private citizen, would be a much higher priority to fix.
