I think half measures can hurt more than they benefit, due to it being used politically as an excuse to not address the root issue by claiming it was already addressed.

The root issue here is excessive copyright terms. Those are the source of the monopoly. We already solved the distribution problem with the internet, now it’s a political issue of reducing copyright lengths. Any other solution will be used by politicians as an excuse to show they did something, or that nothing more needs to be done.

Who cares who buys what once the content is in the public domain. It is a cleaner, resilient, and quicker solution.

Also, it seems unfair that government would be able to dictate what Amazon can and cannot do with its content, but not others, so that is another political fight that can waste time and energy.
