It is about making money. Starlink is a money generating system that makes use of low cost launch made possible by SpaceX.

If it does use up most of the low orbit space it is because SpaceX is the only company that is even capable of launching that many satellites and making money on it. Until there is another challenger there is zero point in complaining, because competition is not even an option.

Since it is low orbit it is self limiting problem. Any low orbit satellite has a limited lifetime of a few years without power.
