Of course you can track down de facto ownership and streams of income regardless of de jure separation. This is a question of political will, not economical (im)possibilities.

Whenever you try making rich people responsible, they move abroad. In Norway, the super rich are becoming Swiss citizens after a recent change in taxation. Unless Switzerland takes social responsibility, they're getting away with it. But if Switzerland does the right thing, the rich will find another safe haven.

However, this is a short term issue. The long term changes require a historical change in culture and policy. Otherwise we're still very much catering to the will of old money and power structures that resembles autocracy.

(I'm just an armchair socialist and no expert by any measure, ymmv.)

What's wrong with saying good riddance to the super rich moving abroad? I'm tired of these threats of the rich and corporations saying they'll just go elsewhere. I say go for it and call their bluff.

They still need to interact with developed countries economic systems, so still punish them there.

Is that not the point?

If the billionaires are net negative and worse than the value they provide, ie billionaires are harmful to society, it seems the easiest way to reduce inequality is just to have them leave.

That's win/win for everyone, they keep their money, you get a society without billionires.
