In a blog post from March 20, 2013 titled "Censorship, Environmentalism and Steubenville," Landsburg spawned controversy when discussing principles on which to justify what is legal. He proposed as a second attempt that "You can do anything you want as long as you're not causing anybody direct physical harm"; he proceeds to conduct an argument by demonstrating that "it would also allow you to rape an unconscious victim if there were no physical consequences". This outcome, in obvious violation of common sense, is then evidence against the second principle. Critics claim this is an attempt to justify rape on an economic basis.
