He's comparing it using your own logic. The "fault" you found was that the design itself was fault. He showed that the inherent design of both the Boeing 747 and Starship both have that same "fault" regardless of how far along they are in proving flight-worthiness. Of course Starship has a lot of work to do, but your argument that because it lacks fin redundancy it has a faulty design is invalid.
