I’m not sure that Starlink is supposed to make money. I think it’s another part of the get Musk to Mars plan. If you are going to a planet with unknown resources what is the easiest way to bootstrap communications. Is it bury 100k of km of wire? Or just plug a bunch of “cheap” satellites into a low Mars orbit? Makes total sense in that light to try it here. I’m not convinced these plans and products are designed to make money as much as bootstrap humans living on another planet.
