The service fundamentally can't support a high density of customers due to limited capacity per satellite. So yes, Starlink is not for people who already have cable in cities or even suburbs. Starlink is for rural areas, and (in the future) vehicles like boats or planes.

You can always send up more satellites though. At some point, the orbit is full, but I assume that is very far off.

  Starlink will already be the largest satellite constellation by two orders of magnitude. To replace cable they'd probably need another couple of orders of magnitude beyond that. And satellites are not the only limited resource; spectrum may be harder to come by.

  The beam width limits bandwidth to a coverage of 1 satellite per ~52 sq km https://www.reddit.com/r/SpaceXLounge/comments/jiu1uq/looks_like_starlink_public_beta_has_begun/ga8qik4/?utm_source=reddit&utm_medium=web2x&context=3 https://www.reddit.com/r/SpaceXLounge/comments/jiu1uq/looks_...

    To be fair, that is the current implementation with current satellites. Hypothetical situations allow numerous things, including narrower beam width.

      Perhaps a silly idea: could the constellation satellites act together as something like a phased array?

Given these limitations, I wonder what the theoretical maximum is for revenue, and how long it will be until they pay back the investment in launching it. It must work out favorably or they wouldn't be doing it, but is this going to make a dent in paying for Mars expeditions?

  Although a large proportion of the world's population live in urban areas, the absolute number of people who don't is still billions of people.

    Keep in mind that of these people a significant portion don't have access to: • clean running water • stable electricity supply • disposable income • bank accounts or means of making international payments So I'd argue that the vast majority of the people you have in mind don't have the means to pay $500 for satellite dish, electricity for said dish, and a double-digit monthly subscription fee...

      This will spawn cottage industry of one guy per village sharing his internet connection for a fixed monthly cost with other houses in the hood. Possibly against TOS but I'm sure no one will police this too hard.

        I understand that's common practice in parts of Africa with cell phones already. Including people on motorcycles driving between villages for more customers, and I understand they'll even drive to no-coverage areas, using the phone as offline storage for text messages.

        As odd as it may sound, I see actual payment as the major hurdle here. While phones come with prepaid plans that can be used with cash only, it's going to be difficult to get payment for Starlink going in many regions, unless SpaceX starts subsidiaries in various regions where this applies and offers prepaid/cash services, too.
