When you think about it, the Federal Government has not exactly been a good steward about the land it "owns" in Nevada. They poisoned hundreds of thousands of acres of Nevada with above ground nuclear tests and almost all of the land they "own" is undeveloped land that provides no benefit to the American economy. If the land were in private hands or at the disposal of the State, then Nevada would likely prosper like the deserts of Israel.
Again you are correct. There is no provision in the Constitution that allows the Federal Government to "own" real property within state boundaries. We are supposed to be a FEDERAL Government consisting of 50 SOVEREIGN states with the rights not specifically granted to the Federal Government to be retained by the States. This would include the rights of ownership over the real property rights within the borders of that State subject only to the regulatory powers in the COMMERCE CLAUSE.
Wake Up Nevada. Bundy is fighting for YOU!
That's a critical thing that so many Americans don't even realize. We are a union of 50 SOVEREIGN states.
We are Sovereign Nations United and not Counties Joined Together.
