Read this by @NSKinsella [link] And check out some podcasts where he explains it. General idea is: property rights should only be in physically scarce things. You can't own ideas, so govt shouldn't enforce/pretend like people can.

If anybody listening would like to take a closer look, I highly recommend Stephan Kinsella's paper "Against Intellectual Property". It makes a very strong, very convincing in my mind opinion for why intellectual property is not a free market institution.
