There is a piece on NPR about Penn Jillette's new book God, No!: Signs You May Already Be an Atheist and Other Magical Tales
Excerpt from NPR piece that mentions libraries:
His discussion of libertarianism is similar: He doesn't believe government has the right to do anything you wouldn't enforce at gunpoint, so (for instance) stopping crime is a legitimate government function, but public libraries are not, since he wouldn't hold a gun on anyone and force them to create a library. Again, some will agree and some won't, but his commitment to this principle is at least something he's prepared to defend.
