One longer-term issue with this in the arts/coding space is that "remixing past work" is often the apprentice-level labor that's necessary on the road to originality and expertise. If we eviscerate the work available for entry-level artists and junior developers to practice on, we can expect much less practiced master-level talent in 10, 20, 50 years. And it's not clear that there's a practical economic incentive to stymie this short-term optimization and its long-term negative consequences.
