As long as professors are allowed to write textbooks, others in their department will be pressured to require them. Every given textbook will have several coauthors at different schools, each contributing a chapter, making the book required for students spread across the country. Ordinarily I'd put my bet on market forces, and I really hope you're right... This is so much closer to monopolistic extortion though, I don't see it changing without lawsuits, regulation, or large donations to University presidents contingent on new textbook policies.
