If it is not stable enough then it is unstable. Where do you draw the bar on stability, if not airworthiness?

Stability means it will return to equilibrium if disturbed, but the issue with the MAX is that it requires a positive force gradient per the Part 25 Airworthiness Regulations, which the MAX does not exhibit in a specific part of the envelope. Stability is not a binary condition. The MAX is longitudinally stable in every part of the flight envelope. "Not airworthy" does not equate to "unstable". Those two terms are orthogonal.
