I think more female developers doing their own thing and making good games is what we need, but I don't agree that "market forces" or "audience demand" are neutral explanations for the media landscape we live in. It ignores the fact that media production and consumption have a reciprocal relationship. (Indie hits demonstrate that there's no lack of demand for 2D games, but publishers simply wouldn't publish them for about a decade after 2000 because they were believed to be unmarketable.)
More importantly, saying "women need to make more good games" risks placing the responsibility for fixing inequality on the people who are disadvantaged.
