Man, I dream of living in a world in which our biggest (or even a top-10) environmental concern is “debris from LEO burning up in the atmosphere”.

Yes, most of us are pretty angry at/disappointed in Elon these days but there are better places to focus than this.

Some chemicals can be extremely potent climate problems. Starlink does represent an astronomical increase in these metals etc in the atmosphere.

Not really. It's a tiny fraction of the same potent ones that come from meterioids, and unimaginably small compared to what just the relatively few solid rocket booster launches. If you're concerned about aluminum oxide's impact on the ozone, you need to lobby for the end of solid rocket boosters log before you even consider demising satellites.
