The current organization of human society runs up against all the same problems you listed - for example, many Americans feel that the current US government is illegitimate, mirroring the feelings of Redland's serfs against their Duke.

According to the current idea of the self determination of people it's the responsibility of those Americans who hold the US government to be illegitimate to overthrow it.

It's not the responsibility of another country like France and help with overthrowing the US government. It's also not the responsibility of France to accept those American's who hold their government illegitimiate as refugees.

If they don't like the society the Duke has established, they can always move somewhere else - again, the notion of exit rights is fundamental to the whole proposal.

Do you think that all African citizen's should have a right to move to the US?
