I think the timeline and price tag are overly optimistic, but agree we can expect massive benefits from the lift capability of Starship. The cheapest big telescopes I could find with a quick trawl are the Hobby–Eberly Telescope and its "clone" the SALT. They cost about $20 million each, compared to similarly-sized telescopes in the $80 million-and-up price range. I doubt there's a project time-line since the 1970s from inception to first light of under 5 years, which would put us at 2029 already. Perhaps the aim should be to have lots of "good enough" unit instruments, rather than one world-beatingly big one that politicians or billionaires find stimulating to throw money at.
