It's not some invented moral perspective, it's also a very practical concern about what is being taught. Cheating in the form of copying other people's work only works in an artificial environment where everybody is doing the same work - you can copy somebody else's answer because somebody else is doing the exact same thing you are doing. Hopefully later in life these students will be doing something new and original where nobody else in the world is doing the exact same thing - which means they will naturally end up with nobody to copy off of. If they didn't learn how to figure things out for themselves, they'll end up useless for doing anything new.
