Maybe by having copyright law we have allowed the authorship of books to flourish and critical mass to drive down the costs of books and allowed people to dedicate themselves to writing books as a profession, or made giving up weekends on a passion project worth completing. Maybe the world you want is less literate/less thought provoking because people can't feed themselves on 'your work is free' resulting in less being written because people who would have been authors are no longer rewarded.

All I know is society decided that copyright was worth the tradeoff of having people release their works and now huge corporations want to change the rules so that they can use those works to creative a derivative that the corporation can profit from.
