Note that one of the suggestions is "use no-cost content whenever possible," ie. public domain or freely licensed works.

Electronic textbooks are another suggestion, one of many. The report does not suggest replacing monopoly-priced print textbooks with monopoly-provided DRM-encrusted e-books that, e.g., can't be printed and self-destruct in a matter of months. That alone would not solve the problem of lack of consumer choice - in fact it would make things worse by taking away many of the completely unregulated uses of a printed book, such as the ability to loan it to a friend.

I'm not disagreeing with your sentiments about the rising cost of education, but merely pointing out that DRM and the price discrimination it allows do not solve this problem.
