Nobody said the Bundys don’t have rights to the land they purchased whether from an individual or from a state or federal entity.
That isn’t the issue. They are grazing their cattle on land that was purchased by the U.S. through treaty. Even Cliven Bundy acknowledges that. What he disputes is that the federal government owns all rights and title to the land on which he’s grazing his cattle.
No, Nevada does not oversee and administer the grazing rights. That would be the BLM, to whom Bundy paid grazing fees for years before he decided he wasn’t going to anymore.
If you want to assert that Nevada’s disclaim of the land in question was unconstitutional, you need to make the arguments outlined at the following link, which I support, BTW.

The land was not purchased by the US government. See post #143.
The Bundy family have a right to the ranch land they bought and to the grazing allowed on public land next to it.
It’s no different than buying a farm with rights to upstream water supply.
