OK, I see.

The government really wants to see what billionaires are doing but they do funny stuff like smurfing or structuring. This is why the government insists on all this AML/KYC shit which hurts ordinary people - not that the government gives a shit about those. Realistically it's not possible to enforce publicity for billionaires and maintain privacy for small folk.

So given the realism constraints I choose privacy or pseudonymity for everyone.
