On that, he is absolutly correct. He's perfectly free to walk to any destination within the United States he so choses. He can drive (he better have a license for that however) or swim, or flp his arms and fly himself. But nothing in Constitution says that an airline, bus or ship must transport his stupid ass anywhere.
He is also free to track down and harass the jackboots that keep his from his natural freedoms.
The correct response to a government that erodes our freedoms bit by bit, is to ruin the lives of its agents, bit by bit.
