Your comment says Starlink deployability makes Starship economically sustainable.
Starship's goals are not merely to be "economically sustainable." SpaceX investors are not investing in a marginally more efficient Starlink deployment system.
You seem to be suggesting that it's a foregone conclusion that from here (economic sustainability via Starlink) that Starship will achieve its much grander ambitions. Is this what you're suggesting? And if so, evidenced by what?
> Starship's goals
Rockets don't have goals. People do. Rockets have features like payload capacity, thrust, cost/ton to orbit, reusability, etc. On which Starship seems to be doing excellently compared to... everyone else.
> SpaceX investors are not investing in a marginally more efficient Starlink deployment system.
IDK what any given investor's rationale is without asking them, and neither do you. Groups, like rockets, are not possessed of singular will.

You seem to be the only one who's said such a thing. However, since you bring it up, I will point out that engineering is a process, akin to science, and success merely takes enough determination and resources to keep trying. SpaceX seem to repeatedly demonstrate the determination, and successfully launching Starlink with Starship provides the resources.
I see what they've achieved already, and expect them to continue applying the same process. I'm not sure how far they'll go. But it's a fun ride already. I trust the process. I'm a fan of the process. You and I get to have this conversation because science and engineering work, rockets fly because science and engineering work. I'm not sure how one would even attempt to argue otherwise.
