Um, ok, Bridget.
But the point is still this: "Live, and let [fucking] live." Pardon the vulgarity, but you and the MotherTucker are both overcomplexifying (I think I just made up a word) the libertarian system. The point is this: if I own the land, and you are on it, respect my authority. If you leave the land, my authority no longer has weight.
Example (I'll try to put this in terms that Ben can understand): I own land, and you are dropping acid on it. I do not want people dropping acid on my land, but I respect your right to do that on your own property. So, do it there. That there could be an overpopulation on the available land is not my [fucking] problem. Buy a condo. You still own the property, or something. Whatever. To figure out how you can own some land is not my [fucking] problem. Just don't drop acid on my property, or I will remove you.
Get it?
