There's an essential big-money-making feature to Starlink that they're kind of keeping quiet about, which is high-frequency trading. There's a straight-line subsea cable from London to New York being installed at a cost of hundreds of millions of dollars to shave a few tens of milliseconds off the latency compared to the more wiggly existing cables, because this makes big bucks for traders.
The propagation delay to and between Starlink satellites is the speed of light so about 50% faster than optical fiber; even allowing for the other latencies, Starling will be able to offer considerably shorter latencies than even the straight-line cable, and they can do it between anywhere and anywhere else -- so, all the financial trading centres. The trading houses will pay *huge* fees for such links, because they can make stupendous amounts of money by being that little bit quicker.
There was a number floating round, and IIRC it was tens of billions of dollars...
