1. The universe is collectively owned by all humans. Decision making must be determined by direct democracy. Global direct democracy has the highest say.
2. Regional sovereignty should be respected, but global direct democracy still has highest say. For example, if the people of Africa democratically voted to take over the rest of the planet, the rest of the planet has the right to vote against that and enforce global democratic will.
3. Global direct democracy can grant temporary regional sovereignty so countries can run their own internal affairs.
