See my comment below. I don't advocate any definition of "ownership". Call it however you want. It is you, not me who is using those concepts when you tell me that some group of people have some sort of agreement by which I must pay taxes, use certain paper bills as a legal tender etc. I am only saying that if I don't hurt anyone and do not want to participate in certain activities, what is the justification for violent action against me?
So please explain what you meant by your original comment.
The justification is that you are on soil that was staked out and is defended by those other people. You're welcome to leave, but you're not welcome to stay without abiding by the rules of the group.
You are advocating a particular definition of ownership: ownership that gives you the right to occupy soil independent of any compact with some other group of people.
So please explain what you meant by your original comment.
