Collectivism and Immigration Controls
Butler Shaffer has a piece at LRC on the basic principles involved. A choice excerpt:
As with government control generally, the power of the state to prevent or regulate immigration is grounded in the doctrine of collectivism. When governments build walls or fences around politically-defined boundaries, they are doing what all other property owners do: staking out their claims to everything contained within. It’s just an extension of the earlier ritual of explorers planting flags on the shores of newly-discovered lands and claiming them for one monarch or another. From China’s"great wall," to Hadrian’s wall, to the Berlin wall, to current efforts to install a fence across the Mexican-American border, governments have built barriers that restrain both their own people and those seeking entry. The principle that allows this to occur is that the state enjoys some collective ownership interest that differs from – and is in conflict with – individual property claims. The state, through no other principle than the coercive force that defines it, is able to transform itself from an agency of protection into a principal interest to be protected!
