Micha: I fail to see how the issue of immigration could be seen as complex, rather than for what it is ….

I think the short answer is this: calling border laws and internal immigration policing a complex issue for libertarians primarily serves a social function, not an intellectual one, in the Mises Institute / LewRockwell.com circle.

The issue is actually, obviously, extremely simple, and Hoppe’s and Ron Paul’s positions are actually, obviously, completely wrong. I suspect that most of those who criticize their positions but pass off the issue as a complex one realize this, but also reckon that it wouldn’t go over well in mixed company to say so in as many words.
