It sounds like you've already made up your mind that it could only be that way, but see my response above if you are actually interested in some more considered discussion of the topic.

I'll just say that I have at least as much faith that people can voluntarily and peacefully reach a workable agreement without using a construct like "The State" as I am that they can do so by using such a construct. In either case, human nature is the ultimate limiting factor.. the State will never be more morally pure, or have more of conscience, etc., than the people who constitute it, IMO.
