A chain is only as strong as it's weakest link. Is freedom in America gone? You only have freedom if you do as you are told. If the powers that be decide you cannot travel then you are trapped. It does not mater if you have your papers that show where you are born, you have to have more and more and more forms of ID
Just take a plane and go through the humiliation of the d h s. Firsst it was metal detectors now it is xray machines the the operators get to see what you are hiding.

Imagine if you were traveling in 1973 then transported instantly to 2009, what do you think you would say? Being searched and humiliated, removing shoes, subject to interrogation etc. We have been slowly-incrementally boiled alive to accept things that our fathers would have screamed at!
