I think we’re already past that point. I can hardly see stars now given the amount of light pollution my city puts off. Little dots zipping around won’t change much.
The thought that would be necessary just to see the night sky depresses me beyond belief.
"We in the city can no longer see the night sky, so it's now an unimportant issue."
SpaceX sky-litter is the first time that i've had my night-sky obstructed far-far off-coast on the ocean; that feels significant somehow.
