>If there's market demand, society can pay real cash money for it.

The point of my argument is that this is one of those cases where that's not going to happen, because we're talking about positive externalities. A generally educated populace, especially in the liberal arts (reading, critical thinking, political science, etc.) is a powerful but diffuse societal benefit in a way that doesn't really have a buyer.

What that likely means is that society needs to collectively come up with a powerful institution to serve as a patron of education and the arts. We could all pay in some token amount of money, and then experts could redistribute it in more globally-optimal ways. While we're at it, that institution could probably take care of a lot of other externality-related problems, like building roads and maintaining some sort of conflict-resolution system. And we should probably all get a say in how it runs. Hey, wait a minute, this sounds familiar...
