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?
