I've always felt the real trick was to make students not want to cheat. Or, put another way, convince them to want to learn. You can't convince them all, but the honest students HATE the heavy-handed anti-cheating mechanisms schools are putting in place. They interfere with learning.
Cater to the honest ones, and try, though various means, to convince everyone to not want to cheat. That $80,000 piece of paper isn't worth jack if you can't pass an interview.
There are plenty of ways to cheat your way through school--and being able to get answers off the Internet is nothing new. Frankly, preventing plagiarism in CS has been pretty much a lost battle for years.
Having to push the entire class to learn instead of just the self motivated is a bureaucratic decision. Everyone is paying 80,000$ to be there, it would be problematic for many reasons to ignore those that seem uninterested. For pre-college education, minimum student performance is usually the strongest metric tied to funding. I don't think the current schooling system is set to let everyone find things they will care about learning and not cheating in. It's not realistic to expect no one to want to cheat. Even the brightest student can feel insecure enough in their ability, feel pressured to cheat if they believe those around them will cheat, or just want to get that little bit more ahead of the competition. Cheating is not strictly tied to honesty.
