Trump cut the size of national monuments in Utah, removing federal restrictions against development of two million acres of land. Supporters chanted “four more years!”, while demonstrators complained that it was a sell-out to industrial interests who want to destroy the land for profit.

The notion that the federal government is a brake against exploitation of resources is absurd.]
In August 2016, the US Court of Appeals ruled that it is Constitutional to ban gun ownership from marijuana users, not because they are considered to be incapable of safely possessing guns, but because the plant remains illegal at the federal level. This is due to a Hawaii statute that makes it illegal to own a firearm if it is forbidden by federal law – another case of states voluntarily surrendering their sovereign rights to the federal government.
