Very observant anon. This has always been a problem but has become worse and worse sense covid whenever rich tourists and investment corps started buying up tons of western land. They are very aware that they are taking over lots of public land and usually the private land is more valuable because of that. There's been a lot of court cases about this especially in Wyoming (the corner crossing debacle), and it the whole process is federally illegal but local legislators/law enforcement don't do much about it. There's some good context here:

The solution in those cases is pretty simple though, just trespass lol. It's not hard and I'd say they deserve it but it doesn't actually hurt them. They deserve a lot worse.
