Sorry, on what basis are you making the claim that 119 is the lowest bound of what they could get away with just so it can fly? I've never seen that be the case

Sorry, on what basis are you making the claim that 119 is the lowest bound of what they could get away with just so it can fly? I've never seen that be the case in aircraft, where everything is designed to tolerances way beyond what you'd see in normal or even extreme circumstances.
