America's first copyright law goes back to 1790, or about 200 years before most people owned computers. It was adopted because people saw benefit in rewarding the people who created books and maps. We've extended IP protection over the years for reasons bad and good.
If you want to get rid of that, you need to explain how we'll get the same or better benefits with your approach. Because from my perspective supporting the current system means means I favor writers and musicians and researchers and artists getting paid for the good things they create over abstract principles.
