Danno, as a general point, if I understood you correctly.
You seem to be saying that people do not have the right to not be aggressed. Your reason for this is that people violate that right? You will agree with me that theft is wrong, yet people steal. The fact that people violate basic ethical and moral rules does not invalidate the rules. Nobody is forced to follow ethics, they can just as well abandon it. Just because our rights are seldom respected, does not make those rights disappear, it's just a sad indicator of the state of society.
The idea is that while a state lives on ethics of double standards (you can't steal but we can), we can't seriously hope for a very moral society. Only when the system of society itself no longer has ethical inconsistencies, will people have more incentives to respect others' rights (and because private defense, restitution, and arbitration is much more efficient than state police and arbitration).
Whenever you say that people do not have rights to not be aggressed, you are essentially saying that violence is moral. However, this is contradictory and foolish. If violence were moral, all wars of aggression would be justified. Indeed, if someone assaulted you, aggression being moral, you should not be able to defend yourself. If violence were moral, I should be able to rape without repercussions. If violence were moral, you wouldn't be arguing with me here in a peaceful manner, you'd be beating me with a stick to get your point across. And yet you're not, so you clearly believe violence is immoral. When I say violence, I mean the initiation of violence.
Violence on behalf of someone's else's self defense (South Vietnam) with stolen resources from american tax payers, cannot possibly be moral or justified. You can't say the social contract and the contract between SV and USA are not linked. The social contract and taxation being immoral, render all actions of government immoral, no matter what their aims, since they operate on stolen wealth.
Then again I could have misunderstood you. *shrug*
