Imagine how cheap medical care would be if all the patents on medical imaging equipment expired. If there were no patents the market still provides incentive to innovate as first movers and reputable brands stay competitive. Meanwhile patents allow big slow companies to sit on their rewards and charge high prices with little real innovation. Things would change, sure. Instead of few large investments we would see more frequent smaller investments. But market competition would still work and natural rewards to innovation persist. Only innovation propagates way faster.
Intellectual property restrictions are a disaster in my mind. And sadly most people believe some basic fairy tale that we were told without ever caring to research if that story is even remotely true.
