I mean, ultimately, that's probably inevitable. We need to decide as a species whether we actually want to have a future in space in a big way. If you actually want to see a future where humanity spreads across the solar system, we're going to need a vast infrastructure in orbit. That's true no matter who is building that infrastructure. So...is it worth giving up that future just for the sake of ground-based astronomy? I would say no. Especially because the same technology and economies that lets you launch enough birds to ruin ground based astronomy also allows you to launch absurd numbers of space based astronomical telescopes.

That seems like a fair trade really. Again, this is just a limitation of the technology. Do you want to see a future where there actually are millions of human beings living and working off Earth? Then we're going to have to give up ground based astronomy. Making low-visibility satellites can help a bit, but it's a fundamentally intractable problem. And again, this is true regardless of who is building that big space infrastructure.
