Rothbard's Law: People tend to specialize in what they are worst at.
Stefan Molyneux is an excellent example of Rothbard's Law at work. He has inciteful ideas about economics and politics, and appears to be a successful tech entrepreneur as well. But instead of focusing in these areas, he's most passionate and focused in the area he's disastrously bad at - philosophy. His Universally Preferable Behavior book is a complete joke, his ideas on families and relationships are incredibly misled, and he's demonstrated profound ignorance overall in the realm of philosophy. I really do think Stefan is an intelligent person, but he didn't exempt himself from Rothbard's Law.
