Definitely a hard choice between an industrial complex generating thousands of jobs and a glorified camera.
If us Europeans and Americans want to look at the sky undisturbed, why don't we build telescopes at home? We can expropriate or block businesses in however big of a radius we want. Or we can buy up all the land around the site we are using in a foreign country instead of keeping the development of the land of the local people. It feels like exploitation.
It's easy to make this about science vs business and I hate light pollution just as the next guy, but it feels gross to shame the local population for wanting to do what we've done with our land already when we can do it at home as well, or pay them to be worth their while to not develop around the site. They should not have to keep their country pristine just because we want to be "pure" with other people's home when we're not with our own. Or pay them enough if it's so important (it is).
Framing does an awful lot of work.
And we're not very far from having many telescopes in space at all. Every year the cost of payload to orbit is getting cheaper. Blue Origin is launching their New Glenn rocket today and SpaceX is having their 7th flight test of Starship in a few days. Starship specifically will drastically reduce the cost of a kg to orbit if it pans out, and this is looking more and more likely.
A significantly reduced launch cost in turn drastically reduces the complexity and cost profile of the actual satellite telescopes.
Operations and maintenance costs will still be much higher even if the hardware and deployment would become equally affordable
Someone just needs to take a page from SpaceX's Starlink playbook and mass-produce telescope satellites. Or someone should pay SpaceX to do it.
