Kessler syndrome doesn’t apply because the orbits are too low to be stable. They have a finite shelf life before they deorbit, after which they’ll burn in the atmosphere. Admittedly, the light pollution is a real problem, but one which should be solved by building more orbital telescopes, not by avoiding building orbital infrastructure.
I would also add that ‘why use many words when few word do’ is usually used to obfuscate bad stuff, so you could potentially pass the vibe check by just saying the above similarity to how you described it here.
