A billionaire cannot exist in 2 countries at the same time. It doesn’t matter if his company is multinational, he isn’t.
If you jail that billionaire, which is not hard as a state if said billionaire resides in your country, you can “convince” him to give even assets in foreign countries.
That’s why they removed his passport.
The comment you replied to originally was talking about why billionaires should support a democratic society.
If the society is not democratic, it would be authoritarian. Therefore what I explained could happen.
