Presumably this would be feasible for most populated areas, but broadband availability is so crap outside of urban/suburban, I bet half of those really remote stations are already getting their Internet over Starlink or Hughesnet.
Now, I think there are plenty of reasons that the satellites (which are already in the sky, presumably) are probably more robust in the face of emergencies than the entire Internet infrastructure.
If I may steelman a good counterargument: "The Internet itself is supposed to be resilient to nuclear war!"
True, but that doesn't mean outages of critical pinch points like AWS, Azure and Cloudflare don't constantly affect even services like GitHub that have huge budgets. A fully robust Internet solution with a ton of high-uptime redundancy in many POPs nationwide would likely cost more than maintaining the satellite systems.
But Cox still has data caps.
