Well, you kinda have to weigh hard things against each other. A while back there was discussion here about the anti Thirty Meter Telescope protests in Hawaii and someone who lives on the big island gave a really good overview. It pretty much convinced me that that telescope will simply not be built there, period. I could not find the thread, sorry.

Apart from that SpaceX is building comms satellites that can handle gigabit speeds at costs around several hundred thousand dollars per satellite or at most the low-millions. Solar and batteries are far ahead from where they were when the Hubble was first built.

As I mentioned in another comment, the real reason is because Starship and Starlink are still not quite real. These telescope projects take a long time to design, fund, build, etc, so realistically they can only happen once those two have proven themselves, which will hopefully happen this decade.
