Does the Federal Government own Nevada?
I am afraid they do. Do some research on Harry Truman's actions on and around June 20th, 1948. He passed some acts of congress into pubic law (quasi law because he certainly exceeded his authority) while congress was on a major recess. The acts he signed and which are to this day PRESUMED to be law deal with extending federal judicial areas over the several States using the names of those states.

To compound the problem everyone PRESUMES they are U.S. citizens and by this proclamation the federal government gains control over the actions of those people who should be supporting their individual states. You cannot have any control over anything when you are a subject.
