According to Article I, Section 8, aside from adding territory as spoils from war, the only way the federal government can own property is if they "purchase" it with the "consent" of the State legislature for the purpose of "needful buildings." Much of the land west of the Mississippi River owned by the federal government was not obtained in either manner. As a result, the Bureau of Land Management unconstitutionally regulates/manages (or should I say "mismanages") a massive portion of the United States.
Confrontations have emerged in Nevada and Oregon, of late, with the Bundy name attached to both situations. The iron grip by the federal government on these lands has led to limitations on land use, be it for grazing, farming, timber or other uses that in our short history as a country was not so much of a concern not very long ago.
