In the 19th century no one would so daft as to think ownership of a random plot of land would give you the right to keep people from traversing it. Someone cutting down your trees, hunting, grazing their cattle or sheep, mining, farming it, yes. Just walking across it? They'd think you were a loon.
And having grown up in Norway, I feel Americans talking of "land of the free" while allowing landowners to block off even their own land is offensive on the face of it.
The ridiculous lengths these hunters had to go to in order to avoid straying onto private land is antithetical to freedom (you still need hunting licenses in Norway; and permission to hunt on private land so there are still potential issues, but worrying about a few meters and the accuracy of GPS to avoid even crossing a tiny little portion of private land is not one of them).
