Jonathan M. Barnett, What’s So Bad About Stealing? The paper skips straight to the proposition that any kind of unauthorized copying (including copying of ideas and expression, but also and of more present interest mechanical reproduction) is theft, then concludes that “Some positive level of tolerated theft is an essential component of any transaction structure that maximizes the social wealth generated by creative production.” I don’t quite understand how you can call copying theft without first establishing that the copied thing is owned.
