Also, Earth's sky will eventually get polluted by things like SpaceX satellites, so this would solve that issue as well.
I know the media likes to hyper-focus on SpaceX, but it should be noted that Starlink is one of the best large constellations in this regard. SpaceX goes far above and beyond the (inadequate IMO) legal requirements for radio/IR/visible emanations, at substantial engineering expense to themselves.

If you really want to get mad about badly-designed satellites impacting astronomy, look up AST SpaceMobile.
I think we will be okay.
