This is a really interesting and well reasoned comment. I'm not gonna try to refute most of it because I actually agree with a bunch of it. But I just wanted to point out that different artistic mediums behave differently. For instance, with PC games (Steam dominates here) it doesn't seem that the "deflationary race to the bottom" that has been happening there (as more and more low quality games get in) has been affecting developers who produce ~good~ games. This can be either because Steam somehow managed to solve this magically or because the PC gaming audience is more engaged in what they buy, either way, not everything you said would play out that way in that market. I think these differences should also be taken in consideration separately for music, movies and books if you want a more accurate result in what you think would happen.
