If you follow tech, or more specifically the state of ISP service around various parts of the world, Starlink will be absolutely huge for a giant chunk of the US. Large rural swathes are still running on single meg connections, with high unreliability.
Much of the US is under monopoly supply as well (even urban areas) so prices are high. This is worse in the countryside as ISPs have no incentive to improve speeds and laying cable is a low return investment.
Starlink doesn't care about remote islands in the Pacific. The big market is domestic.
(Come to think of it on the back of the gun thread, telecoms is another area that's just really messed up in the US because of market distortions via political lobbying... during the last government, the FCC was essentially and unabashedly an extended tool of the telco lobby.)
