This is part 1/2 of an interesting debate between an ancap and a leftist. ActDotTV and last_username are the combatants. I'll be totally honest and admit I had never heard of either one of these people before a few days ago but I really enjoyed this entire discussion and thought the ancap did a great job defending the theory.
They cover lots of ground here and I add extra commentary and thoughts along the way. Of course, the topic of "armed goons" comes up because why the hell not?
