The next step is where the federal government declares all state's grounds to be in full ownership of a private company, so that all land is now effectively foreign and no citizen's rights apply to citizens anymore. An American abroad is not an American. That's an official view.
Eleven years before he became the fourth President of the United States, James Madison said that: Perhaps it is a universal truth that the loss of liberty at home is to be charged to provisions against danger, real or pretended, from abroad. One wonders how Madison would feel about an interconnected world where "abroad" has so thoroughly lost its meaning, at least with respect to Internet-dependent critical infrastructure if not national frontiers. My guess is that Madison would decide that the Internet is, per se, "abroad." --dan
