Unless some knowledgeable people are barking up the wrong tree, the plane is not airworthy without MCAS. It's a pitch stability enhancer, and not directly an anti stall system. It wouldn't be certified under part 25 without it.
You mind providing a source for this "hold the stick all the way back"? They don't land themselves unless you've asked it to file a precision approach.
I don't like it, but why do you assume that goes hand in hand with being disgusted by availability? I'm all for other people having access to it and detectability is not related to impairment.
I'm familiar with the failures you mentioned, but I can't think of an uncontained turbine failure caused by ingestion. The fan, compressor, and combustor take care of debris. Now fan failures yes, but those have to be contained and aren't about to kill anyone.
Ingenstion would no doubt result in a huge maintenance bill, but to be shouting about killing everyone is alarmist.
So which part of your extensive training and sitting in cockpit makes you an authority on the effects of drone impacts? Maybe I should come to you for advice while I'm designing the wings you fly.
What are you smoking? The A380's 3 class capacity is 555. What makes you think a far smaller and lighter plane like the 777x can hold the same or more?
But the 777x may be enough, and the smaller gate requirement may be useful.
