Libertarians are defenders of the free market. On their view, only the free market is compatible with the freedom of each individual to lead her own life according to her own choices. In a book and a series of articles, Serena Olsaretti argues that libertarians are wrong to believe that their commitment to individual freedom justifies the free market. According to her, libertarians rely on a problematic account of voluntary action. As part of her argument, Olsaretti develops her own account (...) of voluntary action. I offer two criticisms of Olsaretti’s argument. First, I argue that accepting her account of voluntary action does not compel libertarians to alter their position in the way that she claims. Second, I argue that her account of voluntary action has unwelcome implications by her own lights. (shrink)
