The fact that a lot of money is possibly at stake is irrelevant. If J.K. Rowling wrote a best seller that had a quote from an obscure author, would he have a right to sue for a piece of Ms. Rowling's royalty action just because she cleaned up financially, thanks only in part to her copyright monopoly? The monopoly formerly known as intellectual property is all about getting a piece of someone else's action by using the State, an institution rightly termed by Mr. Libertarian, Murray N. Rothbard, as "the biggest mass murderer, armed robber, enslaver, and parasite in all of human history." He couldn't have called it the biggest monopolist in history, because it's the only monopolist in history.
