I'm willing to bet that "most" people live in or travel to areas of bad cell coverage often enough that they will definitely appreciate an increase in coverage to literally 100% of the Earth's surface. Starlink capacity and reliability increases will enable a lot more people to ditch bad ISPs, not just people in extremely rural areas, and that can have a big impact on people's lives. Also I would say that international air travel had a big impact on civilization even long before "most" people globally could afford to fly internationally (if they even can today, I haven't found a good estimate for the percentage of people who will fly internationally during their lifetime but it could easily be less than a majority).
