"Why shouldn't people cheat?"

I think cheating should go the same path has the hacking/cracking argument. There are good and bad ways of cheating both in school as well as in real life.

In my opinion someone who develops a sophisticated cheating system that allows to pass a typical brain-dump test has learned more than someone who plays by the rules.

I always believe that the one hacking the system should be rewarded at least by the same amount than the one just following instructions.
