IMO we've ruined the sky already. We can't see all the stars we used to, and new ones (starlink) are visible to the unaided eye. Changing the face of the moon such that it, too, is no longer the same symbol every human has ever seen, feels like a monumental step we maybe shouldn't take. I don't want to see the twinkle of a refinery, any more than I'd want to see a giant McDonald's logo carved into it.
