Why is that unsustainable? You need to present an argument that is more than just "large number! wave hands!"

It's just like the arguments used by anti-renewable energy forces here on Earth. "Large number (of PV modules and wind turbines and batteries)! Unpossible!"

And no, that launch rate does not "wreck the planet".

What's the impact of the atmospheric pollution from both launches and the burn of space craft and satellite's burning up on re-rentry?

The most significant limitation on Starship launches is from injection of water into the stratosphere and mesosphere, but 20,000 launches is far away from that limit.
