> we haven't really seen any sort of space based telescope designs

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.
