Elon Musk

[AFTT47]

The orbiters themselves were labor intensive because of those damn heat shield tiles. They never did get that problem really licked.

Musk also didn't solve this problem on Starship as it burns in the atmosphere upon return, and there is no reason to believe that he will solve this since he doesn't possess some knowledge others don't have.

As I pointed out before, Starship is in development. You understand how the SpaceX development cycle works, right? I assume you do since you are such an enthusiastic critic. Just in case you don't:

SpaceX advances the design to a point and then launches with that design and sees what happens. Tweak the design based on the results and try again. Rinse and repeat. Eventually, you arrive at your goal. Definitely not the way NASA does it but it sure worked for Falcon9. Starship is much more ambitious so a longer cycle is to be expected. Based on SpaceX's track record though, I'm confident they will succeed.
