Stalls, on the other hand are part of standard instruction. Recognizing the beginning of a stall early and preventing it will prevent the spin.
Weird things can happen with big downdrafts and wind shear, but those aren't terribly frequent and probably a spin is less critical to practice than stall recovery. But it's a very different experience to actually feel the forces and see the world spinning than you get in a sim. Also it's a lot of fun.
