This is pretty much it in a nutshell as far as I can tell. If the sensors don't agree, and MCAS switches off, then the pilots have to be ready to deal with the plane trying to pitch up and stall on their own. When would that happen? Take off and go-arounds. Pilot is coming in for a landing, something goes wrong (too much cross wind, plane on the taxiway, Etc.) what they do is they pull back on the stick and push the throttles up to max to get into a climb. If MCAS is disabled and the pilot hasn't trained to fly the plane without it, there is a risk it will pitch up and stall onto its tail. Not a good place to be.
