Wonder if the Spaceship will allow Musk to send up a serious satellite-based backhaul option. Sounds like there'll be some money to be made there, perhaps sooner than anticipated...

You mean SpaceX? AFAIK Musk is nothing more but a shareholder at this point. Maybe you mean Gwynne Shotwell

  You are wrong. Musk is CEO, Chair and CTO according to Wikipedia.

    And Shotwell is currently the President and COO.

Replacing entire bundles of fiber connectivity that is most likely in the 100 Terabit range per cable with space based solutions is not economical. Laws of physics still apply even to space based connectivity technologies.

  Yeah I mean the whole point of my post is that maybe with laser inter-satellite links and a super heavy lift capability it might become economical at least for some use cases. E.g. the Pentagon might be quite interested.

Best estimates I've found is that Starlink v2 sats have an aggregate capacity of 80Gbps each. AAE-1 alone has a capacity of 40Tbps (the article says terabytes - that's wrong; EIG is <4Tbps, TGN Atlantic is ~5Tbps), and so assuming the numbers I found are right, you'd need to be able to aggregate bandwidth across 500 Starlink sats for uplink, 500 more for the downlinks, and whatever number you need for laser links between the endpoints. There are at lot of submarine cables[1], though, so while I don't doubt that there will be people looking for contracts to use Starlink for some degree of extra redundancy and worst-case offload, the primary redundancy for these cables will be other cables, along other routes at least until Starlink gets a couple of generations further.
