When the benefits of creating a new country outweigh the costs (to shareholders), does it fall within the fiduciary duty of corporate leaders to form a new country?
If you don’t control the planet you’re just waiting for your competitors to crush you.
To your point though, what if a few or even all Fortune n companies formed countries (or one country together). Who would the sanctions really hurt/benefit? I doubt it would hurt the corporate nation states as much as the others.
