According to the authors numbers it'll take at least 20,000 launched to put a million satellite's in orbit

And that's before you consider the issues of operating a DC in space

It's just a a load of nonsense

Why is 20,000 launches a load of nonsense?

20,000 launches is 11 Starship launches a day for 5 years

It's an unsustainable rate and even if we do get to that rate it'll wreck the planet

		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".
