A lot of us get to live thanks to IP protections too. >90% of Hacker News readers I'd say, including myself. Software development is all about IP, most of art too, and medicine, and chemistry in general. Who wants to pay people to develop software, or even design new hardware or medicine if competitors can take all that hard work for free?

There may be alternatives to copyright and IP in general, but that would require dramatic changes to society, and maybe not in a good way. What you would get is essentially communism. Rejection of intellectual property is a form of rejection of private property, which is at the core of communism. Problem is, looking at past examples, it didn't work great.
