It does have minimal marginal cost, as long as you live in the right place on earth, without many other customers next to you. Once you exceed, fairly limited amount of people that can use it one cell, you need to grow massively your fixed cost, as you need to grow the whole constellation or just won't be able to grow. Time will tell if that will add up. I don't think it's obvious it will.
