A XX,000 satellite constellation going full debris cascade is going to leave a mark on LEO for quite a while. And that debris will have to traverse the orbits of the space stations and Hubble and who knows what else as it deorbits.

It's pretty common for the SpaceX superfan to completely disregard the impacts of such a thing. I'm not sure how they do it but they seem to be able to filter out any and all bad outcomes when their favorite corporation is involved.

I guess it's their super power.
