I find the argument against intellectual property compelling. I’ve read in Boldrin & Levine’s Against Intellectual Monopoly (offered free online consistent with the aims of its authors’ argument) and listened to Boldrin’s Econtalk interview twice.
Boldrin in the interview and in the very first page of his book stresses the potential boost to innovation following abandonment or weakening of intellectual property rights.
This makes intuitive sense to me. Royalties and the legal fees necessary to fight battles over patents and copyrights are costs that prohibit innovation. Reduce those costs and innovation will flourish.
