Copyright should be commoditized. A possible first step could be giving copyright owners a single obligation: you have to sell what you own. That thing you have must be available on the market.

This rules out negotiations. They imply a possible negative result, hence the thing is not really available. A public offer, however, is fine.

This thing alone may change the situation quite a bit. Imagine a true market for textbooks or streaming media where every provider has the same selection of titles and has to actually compete.
