The states are integral to the US Constitutions. Once recognized, they cannot be dissolved or have their leaders/representatives replaced short of very narrow legal issues or martial law. The states arguably exist above the national government.

Cites and other public entities in a state are defined and authorized by the state. The state can step in and even quash them anytime they feel like it. Look at the City of Bell in California and Benton Harbor MI.

Direct defiance of Federal law has its risks. The gun stuff is nothing compared to what is happening with Medical MJ. States are authorizing it, regulating it, and taxing it. The Feds are raiding it.
