A few hundred people of this guy's means and mindset, and they could make all of rural Wyoming totally inaccessible (while only "owning" half the land).
It's well worth picking apart this guy's legal sophistries, as he's leveraging all the aberrations of modern legal philosophy to play the (local) tyrant here.
Worse, he’s not from Wyoming. He got rich from another area and moved there. He doesn’t support the local culture and people, that’s why migration destroys.
