Prof. Daniel D'Amico discusses several arguments for and against government enforcement of intellectual property, including trademarks, patents, and copyrights. He explores both moral arguments (deontological) and cost benefit arguments (consequential), dedicating most of his time to consequential arguments. He finds that, in general, intellectual property is difficult to enforce and is inherently an anti-rival good. As a result, he finds no compelling case for government established intellectual property law.
