*I* am not smarter than that. But *you* might (just might) be. "Eliezer says so" is strong evidence for anything. I'm too stupid to use the full power of Bayes, and I should defer to Science, but Eliezer is one of the few best Bayesian wannabes - he may be mistaken, but he isn't crazily refusing to let go of his pet theory. Still not enough to make me accept MWI, but a major change in my estimate nonetheless.

As a side note, what actually happens in a true libertarian system is Europe during the Industrial Revolution.
