I think you are downplaying the problem. They are already reporting issues with Starlinks and there are "only" a few hundred of them right now, Amazon wants to deploy 3k low orbiting satellites.
Look at this list: https://en.wikipedia.org/wiki/List_of_astronomical_observato...
The very large majority of the world's observatories are doing wide-field astronomy.
This is not scientific progress, this is just two billionaires trying to one up each other and muscling their way around the world to rub their egos.
Starlink claims to have other objectives. Why do you think their stated objectives are dishonest?
This is a gimmick to sell the imaginary joy that you can go anywhere remotely and enjoy the pleasures of the modern connected world. There are already niche providers for Satellite services that users can use, if they are truly isolated and are able to afford internet.
There is no sense in having all of this infrastructure duplicated and done via RF transmission over a low-orbiting constellation (with all the losses and realibility issues around it), if it can easily be achieved through expanding the existing infrastructure.
The only use-cases that this serves are high-income people that want to go off-grid but are unwilling to sacrifice high-bandwith, and military deployments (Which SpaceX does not hide as an objective).
Sure some architecture stays ugly - but preserving the aesthetics of a sky(line) ranks really low on my list of things that are worth stopping progress over.
It distracts from better objects like the Louvre and others.
