Yeah, you can end my life. What you cannot do is take away the life I have lived. This is the difference. My life lived I do own.

As to the rest of your questions, I agree with you. The way one governs themselves is government. If two people agree to govern themselves according to some rule, they form a mutual government. Government is nothing more than an agreement.

I am not aware of any misconceptions that may be obscuring your vision.
