Starlink is actually extremely expensive and slow. About $600 for the dish and about $100 for speed slower than my cable plan in 2003 as slow as 25Mbps. Worse even though rural areas are spread out a good chunk of people tend towards smaller clumps close enough to be sharing the same bandwidth. The entire constellation doesn't scale to supporting a reasonable experience to even a fraction of rural America let alone planet earth.

You still basically need to run fiber into every town however small.
