Wellll, that's not actually how it works. Capital expenditures are only a fraction of total expenses, which is only a fraction of annual cash flow. For example, in a previous life I worked at a VoIP company. At that time, our technical infrastructure was largely paid for. We had a couple of million subscribers and were struggling financially. The lion's share of cash flow went to Customer Service, Advertising, and Debt financing and repayment. (Disclaimer--I haven't kept up with the company and have no idea how they're doing now.) It's very difficult for an ISP to make much money at $30/mo per customer, unless you go the Google route and only provide automated customer service. That's why established ISP such as Verizon are losing interest and selling their operations to bottom-feeding companies like CenturyLink. All of the money is in Mobile. I can't see SpaceX itself actually providing the retail experience. It's entirely foreign to how the company functions. I'd see SpaceX either contracting to provide technical services (like Level3), or wholesaling the product to sort-of MVNOs (Mobile Virtual Network Operators). If wholesale, it could be a captive sister company (Musk does have the retail experience) (by analogy, like Mobile PCS which is owned by T-Mobile), or to independent operators (analogy being Virgin Mobile). I don't have any deep insight into the market, but some interesting possibilities would be a hungry cell carrier like T-Mobile branching out into ISP service, hoping to provide more attractive land/mobile bundles.
