I wrote a post about this earlier today asking some of the same questions - basically, what's the point? Why are "anarchists" taking up statist arguments and claiming that we ought to have certain preferences about statist laws and policies?

This entire "debate" makes absolutely no sense for anarchists. It's just another way for some people to pretend to be the smartest people in the room...except they're making themselves look pretty foolish and childish while simultaneously making "anarchism" look quite statist itself. It's a lose-lose for everyone, in my opinion.

The one good thing - if we can call it good - is that it's exposing more of the nationalists and even some of the outright racists that have been infesting libertarian circles for a long time.
