Anarcho-capitalists are kooks. They're so emotionally attached to capitalism as an ideology, any criticisms or suggestions of its imperfection results in cognitive dissonance. They cannot have coherent conversations outside of a cult like hero worship of personalities like Ayn Rand (who cashed her Social Security checks anyway) and Joseph Gamabos, who weren't even the true believers the anarcho-capitalist cult today have become. Naive is a very charitable term for them.

I'd say it's stupidity. In the Dietrich Bonhöffer way of thinking. Stupidity in large numbers (perhaps tribalism), is a greater danger to good than evil.
