I think you've put your finger on another economic scatology here. There are these economists who run around saying that intellectual property rights need to be stronger, because having some copyrights promotes innovation. To an extent that is true. If you're an innovator and you have no patent protection, you're not going to innovate. If you're a musician and you have no copyright protection, you're maybe not going to write your songs. But copyright protection and patent protection can both easily be too strong too.
