His point had nothing to do with the termination system.

The rocket tumbled for four complete revolutions. Most rockets will be destroyed by inertial and aerodynamic forces well before the first revolution (they are designed to withstand forces along the major axis, not significant side forces).

It was helpful from an aerodynamic force POV that the rocket was well over 100,000 feet before it started to tumble. Still, the inertial forces when the full stack started rotating must have been huge.

That's not exactly a direct response though to the question unless you're suggestion is that SpaceX's destruct mechanism consisted of expecting aerodynamic forces to destroy the rocket during a tumble.

I interpreted Musk's comment to reflect the fact that rockets generally will be destroyed if the tanks lose pressurization and/or the rocket tumbles. The (load bearing) tank walls usually cannot support major side loads. The Starship stack needs to be a lot stronger than "usual" rockets to withstand the rotational forces and aerodynamic forces involved in landing them.
