Neverfox, Gary: I am not for closed borders. I am not for the INS. I am for its abolition. My article was “an argument for”–I was trying to present the best argument I could think of for some mild limitation on immigration by the state controlling roads for the benefit of its real owners (to simplify: current US residents and taxpayers). Gary, the “authority” (arguendo) would come from the owners (the US taxpayers) who have a natural ownership claim to the road. But in the end, I am not in favor of the power of the state being used to limit immigration.
