The target cost of getting stuff to LEO using Starship/SuperHeavy is $2m per 100000kg, or $200k per Hubble. It would only cost $43 million to launch the light-gathering equivalent to the ELT. Now, $20/kg to LEO is very optimistic, but even at 5-10x that rate, a more believable $100-200/kg, that would still make the launch possible for 200-400m, which is roughly the cost of a Delta Heavy launch. Scaling this up, a 100m telescope (The OWL) would be 1,735.69 Hubbles and cost $350m to launch at the optimistic price, but still less than $3.5B at the believable price.
Basically, if Starship is successful it could have a dramatic effect on astronomy. 216 Hubbles may sound a bit insane, but mass producing them would drive the cost for each down considerably. Without the atmosphere, you don't need the fancy laser-actuator correction mechanism, and you certainly don't need to fight local activists for one of very few locations worldwide where you can plausibly put these things (AFAIK, there are only 3 such locations worldwide - Canary Islands, Cerro Amazones and Hawaii). Not only that, but if you had a constellation of Hubbles, they could be spread out and use interferometry to construct a telescope larger than the Earth (this is the technique that Event Horizon Telescope used).
So the question is, is it possible to design a standardized, flatpack hubble-sized mirror+cam sattelite and pull it off for the price of a regular telescope? At ~1.2Eur for the ELT, that would imply $45m per "hubble". Seems doable.
