Yes, the plane might require expensive training and expensive modifications. It may even have to get completely scrapped if the changes are deemed uneconomical to deploy.

With all the different government agencies going to be manually inspecting the updated plane themselves, the MCAS problem is going to be put under a microscope by dozens of different countries and if they do approve it and deploy it, then I am going to take there word for it as having mitigated the MCAS problem and won't care about stepping on a 737 max as its track record outside of this 1 problem is fine.

If it does not get approved or deployed, then who cares because you won't even have the option to fly it as it will stay grounded. Regardless of what happens, checking what plane I will be flying on will not impact my decision when choosing flights.

I think there's something here you're missing:

What if it does get approved, but only by some countries? So, for instance, suppose the US approves it, but China and the EU don't? Then, it probably won't stay grounded, because this plane is usually used for shorter-distance travel. Southwest Airlines, for instance, exclusively uses 737-type aircraft, and all their travel is domestic US, so an EU ban wouldn't affect them at all.

I for one wouldn't feel too confidant about the FAA approving this plane with the EU regulators refusing to, considering what a criminally-negligent job the FAA did in approving it in the first place.
