I get where you're coming from but we haven't really seen any sort of space based telescope designs that take advantage of the Falcon launch paradigm of cheap and reliable launches.

Some sort of modular telescope array that could be launched in pieces and self-assemble in orbit. Something that improves in capacity as more pieces are added.

Everything seems to have stalled in this field, as if it's just waiting for a Starship which may never come.

We’re only starting to truly mass manufacture satellites. A world with millions of satellites means one with lots of satellite production and design economies of scale. (Same for all manner of sensors and optics.)

Or it may. We’ll know in a couple years. Building a scaling production system for Falcon right now would be silly.

And if Starship never works out, we probably don’t see millions of satellites. It’s a fundamentally tied problem, which is why I say the analysis is incomplete.
