Um, how would you conduct spin training then? Spin certified airplanes tend to recover from spins easily enough, so how are you going to make pilots "work for it"?
Edit: I just saw the quadrouple-post you made, about flat spins. I'm not even sure how you would put a 172 into a flat spin which makes it a bit hard to do in a training environment.
I am thankful I went to a school that made us do spin training to get our PPL. Learned a ton of the lesson and it was one of my favorites also. I did the spin in the Decathlon, and like TwoTwoLeft 's video, the nose was pointed almost straight down. How did the pilot in the first video get his spin to be "flat"? It doesn't seem like that was his intention.
Spins are so scary.... But seriously, I do spins a few times each week.
You don't seriously think spins are scary do you?

For educational purposes, notice the spin attitude vs the one in the previous video.
