Im sorry but youve managed t contradict yourself, you claim that no one owns the land, then in your next post claim that some of your friends are landowners
To cap it all you claim that no one has challenged you because you are the helpful kind of trespasser, you claim that you help the landowner to repair damaged gates and clear fallen trees. Clearly you are in two minds; you allow that your friends are allowed to own land because they dont stop you from trespassing on their property. But you say no one can own anything unless they make it for themselves. I own my car, but I didnt make it, I own my house but I didnt build it, I could go on.
Land is/can be owned, nothing you can say, do or think, can deny that. You are entitled to you opinion but not your own facts Daniel Patrick Moynihan.
Land ownership is a fact. So the owners of the land can pretty much tell you what you can or cannot do. Nothing in your opinion, your refusal to recognise the rights of land ownership, would stop you from being prosecuted, should the aforementioned land owner decided that you were an unwelcome guest.
Im sure this part of the post is meant to show the forum what kind of person you are, And believe me it does, just not how you think it does.
