The Swiss nation bank and other central banks should also do something similar. They are loosing control to private foreign corporations which decide what you can and can not purchase. Not based on laws but on risk.

One of the jobs of the SNB is to enable payments. But because most people are using digital payments now they are loosing this ability and control.

If you get sanctioned by the US you loose access to all digital payment systems. In Switzerland where access to a bank account is a right written in the law you can only use one bank (Postfinance) and this bank has to limit you to basically a useless account (No wires, no credit cards etc.) because even the internal digital payment system (Twint) touches some US system.
