If you're designing a collection around early punk, someone will have to represent the Sex Pistols. When you're thinking about Austrian economists, the person who's going to step into the shoes of Johnny Rotten is Ludwig Von Mises.
After he passed, his wife Margrit said this, "His most eminent qualities were his inflexible honesty, his unhesitating sincerity. He never yielded. He always freely enunciated what he considered to be true. If he had been prepared to suppress or only to soften his criticisms of popular, but irresponsible, policies, the most influential positions and offices would have been offered him. But he never compromised."
To us, that's John Lydon. Von Mises led. Von Mises had his friends, but he also had his enemies. This 1995 Reason interview with Milton Friedman, (excerpted on Von Mises wikipedia) can help make that argument.
