Even if you "actually care to learn", this is a huge mental shortcut and you're deceiving yourself if you think deep learning is happening from looking at the answer.
On top of that, the pressures to just finish the coursework and move on to your other homework due tomorrow seems pretty high. Your suggestion means we're no longer coddling/shielding students, but we also aren't actively helping them, are we?

My suggestion is just the former, it doesn't imply the latter.
That's a major reason why employers have traditionally valued degrees from research universities, even if they are not particularly highly ranked. Being able to thrive in an environment like that shows a degree of independence and initiative.
