I agree with you that most don't follow natural law. That's the cause, the government or external control is an EFFECT. Before I would rage against the government, but you're right, most people don't give a rip about right and wrong: that's the true great work, to educate them and encourage them to live better.
The government cannot enforce natural law because they BREAK natural law, through theft relabelled as taxation, through initiating violence against anyone who disagrees with its 80,000+ pages of laws.
We don't need a group of rapists to protect women against rapists. Do you see my point?
Finally, thanks for your compliment by saying I should run for office. However, that won't do anything. That's like joining the Mafia and trying to turn it into a charity from the inside. Won't happen. Also, by running for office I would be giving my implicit thumbs up to that institution, which I can't do.
The point I'm hoping to convey to you is this though:

Do you know why people form governments?
