Sadly, there still seems to be a great deal of confusion both inside and outside of libertarian circles about libertarianism’s relationship with the immigration issue. This is no mark against someone who has simply not had it explained to them, of course. The position is not entirely obvious to the casual onlooker. The persistence with which some insist on clinging to falsehood however, I find quite troubling.
The layman’s assumption would be that libertarians favor open borders. This is an understandable mistake. Libertarians are not big on having the government do pretty much anything, and since governments do control political boundaries at present, it makes sense one would assume we favored their abolition. This is not a completely incorrect assumption, but it requires some important details many seem to leave out. It would be more accurate to say we favor privatizing borders, than to say we favor their abolition.
