The physical book comparison is interesting. Imagine there would be a way to publish physical books with DRM that all publishers would embrace.

In the case of DRM, many people have been talking about this problem for a long time. It's not a matter of consumers not listening, it's a matter of alternatives not developing in the market.
DRM in video games is a lesser problem as alternatives did develop. Steam, the #1 platform, doesn't enforce DRM. GOG and Humble Bundle have been running their platforms on mostly DRM-free games.
Who do you fault for alternatives not developing/not catching on in the ebooks/video world? Consumers for making the wrong choices? Companies for not trying hard enough? Governments for not regulating consumer rights?
