Yeah, education should be free. Record all lectures and put them out there. Charge a small fee to view them if you must but lecturers repeating themselves is not my idea of a great use of their time. Yes, I know lots of lectures are already published.
Watching non-interactive lectures is a small part of the overall experience. I'm not commenting on whether the experience is 'worth it', but assuming the only thing people get is the ability to watch lectures doesn't make the point.
On the other hand, many people act like "talking to professors over beer" (or to your classmates, for that matter) is supposed to add "value" to the college experience, when it's perfectly possible to get at least a bachelor's and a master's without ever doing that (source: I did).
