I also think about the oppressive nature of copyright. Not in all cases, but in some where the owner ends up exerting way too much influence and power over any use or interpretation of their IP. I could see a highly technical system of royalty management and payment streams reach a tipping point where it becomes a burden to creativity and new ideas.

There's a good read on this called "Copyrights and Copywrongs" that traces the history of copyright law in the US over the past couple centuries, and its relationship with creative output. It's interesting how perspectives on this have changed over time (and depending on where you sit along the royalty chain)
