This is another example of Tom Woods at his best: a "real deal" academic PhD historian and ultra well-connected with facts and the Libertarian community, but also one of the most down-to-Earth chummy people I've ever encountered, who takes the time to explain complicated multi-faceted historical and economic concepts in the kind of plain manner which anyone can follow.
He's one of the very first people I always steer others onto when they express an interest in Libertarianism.
