This monograph is justifiably considered a modern classic. Stephan Kinsella caused a worldwide rethinking among libertarians of the very basis of intellectual property. Mises had warned against patents, and Rothbard did too. But Kinsella goes much further to argue that the very existence of patents are contrary to a free market, and adds in here copyrights and trademarks too. They all use the state to create artificial scarcities of non-scarce goods and employ coercion ina way that is contrary to property rights and the freedom of contract.
