The video overflows with the usual rhetorical flourishes of a Libertarian, who would never consider doing what he says other people should do. What possible benefit for anarchists comes from a dialogue with pro-property minarchists? As you can hear from the video, it's all about rights and laws and bad people, with a few nods to something he calls "the ruling class." Nothing about the institutions the state relies on to maintain class power other than to mention excesses and the imposition those excesses represent to ... what, exactly?
Self-preservation and self-defense are assumptions to most anarchists. The video doesn't really go beyond that, but instead tries to shock folks with the slippery slope of police abusing their legally sanctioned power to Hitler and Stalin. Really sophisticated argumentation, dude.
Libertarians are annoying for a thousand and one reasons, and the video is just one more example.
