More regulations would just have the result of cementing a monopoly for Spacex.
A lot of astronomers disagree.
How can this be resolved?
Maybe water rights really are the best model for this, but it’s a terrible model as demonstrated everywhere there are water rights. I’d like to think there’s a more sensible approach.
Yeah it turns out that "divvy up finite resource" is actually just an intrinsically nightmarish problem when it's something no one intrinsically owns, didn't create, but needs nonetheless, like water and land.
I'm still checking the maths on how bright a million satellites in a terminator-following SSO would be. I'm getting very big numbers. But then, the (vague and aspirational) suggestions I'm seeing right now for SpaceX are in the 120 kW range, which is huge, and lining up a million of those is enough for a contiguous ring just under 10 meters wide (how much under is "just under" depends both on how efficient the PV is and how high in LEO you go).
Regardless of if they're all in one orbit or spread over in multiple orbits at different shells that are all terminator-following SSO, from the ground you're getting a train of things with somewhat higher brightness than the ISS, with a fairly small apparent separation that (I tentatively think) becomes less than your eyes can resolve at at least one point in the sky (if there's say 50 shells, where those 50 get close to crossing).
