The point is you can't just take the MCAS out of a MAX and retrain pilots - it's a vital fix for handling characteristics that were unsafe to fly, full stop. Without the MCAS, it - quite rightly - wouldn't have been allowed to carry passengers at all. It's an important distinction with wide implications.

(However, it does strike me that an MCAS-like device, an automated trim to paper over the inability of the airframe to fly stably under all flight regimes, is a fundamentally unsafe device and should never have been allowed in the first place, let alone with such a poor sensor suite. The MAX is an irredeemably unsafe plane, a result of bolting new engines on an ancient airframe that was not designed for them, and the resultant pile of hacks.)
