As long as the externalities are paid for, I don't see the problem. Musk has made the world a worse place in many ways, but I don't see how this is one of them.

this thread is about satellites cluttering the night sky. Is SpaceX paying for this? Not the mention the CO2 emissions of all the rockets.

You're right. Private launches are undertaxed. Launch cost used to be so prohibitive that it didn't matter, but regulation hasn't kept up.

I price the externalities at infinite price. They cannot be paid.

You're saying if someone offered you a billion dollars to launch a satellite no different from most other satellites already in space, you would say, "No, thank you, madam!" I'm skeptical, but if you insist, I'll take you at your word.
