I get that he's "diversity averse," but he certainly has a right to dislike people outside of his own race and culture.
I actually think egalitarian-minded folks could potentially benefit from an AnCap society in that racist shitheads would group together and leave everyone else alone.
What I want to know is if Mr. Martel actually grasps how alone he'd be, considering MILLIONS of 3rd world peasants would likely flock to stateless territories in order to take advantage of free market opportunities, zero taxes, freedoms, etc. Even IF conditions in AnCap societies were worse than they are now (in the US for example), they would probably still be much better than most 3rd world countries. This would incentivize a mass influx of (in Mr. Martel's mind) "undesirables." And because they'd be desperate for any work they could get, larger employers could exploit the fuck out of their cheap labor. Employers could even exchange housing accommodations for labor, effectively creating small Worker Communities. Since these businesses are getting their labor so cheaply, they could potentially outperform their competition, expand, buy more land, hire more cheap labor, build more communities, and go from there.
There's no way Mr. Martel's racist Homeowners Association(s) and land owner(s) could completely insulate themselves from this type of thing.
Even worse (for Mr. Martel), wealthy families and ambitious entrepreneurs from filthy brown countries would be drawn to stateless territories (no taxes or minimum wage laws? Yes please), bringing their filthy brown families and filthy brown associates with them.
There's no reason our dear Mr. Martel should expect any of these filthy brown people to keep a "safe" distance from his fat, pasty-white ass, unless he plans on never leaving his fat, pasty-white neighborhood (or the surrounding fat, pasty-white neighborhoods).
