Every layer of this type of complexity adds risk. Seriously, MCAS was designed to increase safety, but instead added risk.

It may be better to go to full automation then to start having various controls be locked (with the issues around those added mechanisms).

There are already LOTS of situation on airbus in particular where the plane simply will not do what you tell it. Overall this has saved a lot of lives (envelope protection etc).

You CAN almost always override / remove the safety envelope (pull breakers to get to direct law etc) but why. These plans can now be flown by relatively junior pilots (or in this case by folks with potentially fake pilot licenses).
