The largest number of monarchs were not elected.

True, some had to consolidate some of the ruling families/powers in their nations, but that is hardly a vote of the people.

I would go further and say that we establish governments, not because we want to abdicate responsibility, but because it is more economical for the protection of rights. But only if that government remains restrained, which they never do.

Absolutely, the world will heal when Christ sets up His kingdom. 

Interestingly enough, I'd like to do more reading on Bruno Leoni. He advocated for a system of judges, similar to Israel before they established kings.
