I used to wonder the same thing and then we bought a vacation home and experienced no cell service in an area close to a major metro. It's only a 40 min highway drive outside a top 20 U.S. big city. Our street is only 12 mins drive from a major interstate highway with the usual suburban superstore sprawl (Target, WalMart, Home Depot, Costco) so it feels like we're in the middle of 'civilization'. But once you turn off the highway, that last 12 mins gets both beautiful (with rugged hills) and also very empty.

Five mins from our house suddenly cell service from all the providers gets very spotty. If you live near the top of a hill facing the right direction, you can maybe jury rig a cellular antenna on a pole. There is legacy POTS phone service via 60 year-old copper but few use it because it's only ISDN barely faster than dial-up and >$100/mo. Otherwise, there was no option for reliable residential phone/data/text service until Starlink became available in our area a couple years ago.

So everyone in our entire area has 2M radios to communicate in emergencies because in four years we've had two fires come close enough to close our roads, been snowed in twice (without power) and a small bridge got damaged in flooding blocking vehicle access in and out for four days. We can't even see any of our neighbor's houses from our property yet several times a year we need to get extremely local information from, and coordinate with, people we'd have to hike to visit. And it's usually because something is happening which takes out local power and/or road access. But the old 2M radios have to be monitored in a real-time which feels really antiquated. So, to me, inexpensive LoRa that could enable store-and-forward messaging and conditional unattended alerts suddenly sounds very useful.
