It's not some convoluted thing, a lot of systems, probably most you encounter in adult life in an industrialized society, depend on essentially voluntary cooperation. That's not to say the way universities work is somehow optimal but again, as you point out yourself, you don't have participate if you think their methods are too poor to bother with.
