The problem is that you can't disable that system: the aircraft is not certifiable without, that is to say the risk of stalling is considered too high without that system. Because that system may have caused two planes to crash doesn't mean that it didn't prevent the ~350 other 737-MAX flying from stalling.

So if the MCAS is indeed the cause of that crash, I expect fleet grounding until the system is fixed. Assuming it is fixable, which I think it is, but might require more than just a software fix.
