I think the only market Starlink will serve is the remote market. And there just aren't enough customers to make it pay. Even in little Creede I have fiber to the house. I have it in Longmont too. So I get gigabit in both locations with 1/10 the latency (consistently <4ms ping times vs <45ms with Starlink).
Iridium went with this notion too and lower cost, easier deployable technology found a way to upset the plan. I can almost promise that the majority of people won't even have fiber, cable, or DSL in 5 years. We are going to be getting such incredible service through cell radios that people will cut that cord too. 5G speeds and latencies are going to make even my fiber look like a 56k modem.
And it is just so easy to drop another tower wherever you need one that the only markets Starlink will attract will be oil/gas, shipping, and remote.
