Not bad but that's guesswork. You have no real understanding. You have also forgotten that we are comparing terrestrial telescopes to orbital ones.

For example...

>They're hoping Starship costs will be under $1 million per launch, with a payload capacity of at least 220,000 pounds. That's like $4.50+ a pound. That's 342x cheaper.

The launch costs of a terrestrial telescope is zero.

Also, are those SpaceX numbers? Because Elon Musk also said we were going to get full self driving every year for the last five years. He even got people to pay for it. He has been caught and punished for lying by the SEC multiple times.

If those numbers are from SpaceX, then they are untrustworthy to the point of complete irrelevancy.

>They'll save a huge amount of money by using cheaper and heavier materials.

No, they can't. Low mass is also useful for adjusting the orbit and aiming the telescope. Making it heavier is detrimental. Unless, of course, it's on Earth, in which case you can use very heavy materials like concrete and steel.

>Then there are all the costs involved with designing them to fold up like an origami to launch in the currently available fairings and then unfold once they get into orbit.

Terrestrial telescopes do not need to unfold.

>Adding extra backup systems and propellant tanks won't be a big deal.

It will, because you will need more propellant to move the greater mass.

Launching a telescope might be getting cheaper but it will always be cheaper not to launch at all - and although you have made a decent, if layman's argument, I don't see a 1000x change there.
