You: "I have heard this stuff for 25 years. Even as elected official. "Wimax will be good enough for the remote areas!" "3G will be good enough!" "4G!" "You will never need anything better than 5G!" And 640K ought to be enough for anyone. Sigh."
Are you serious? We're talking about "now". What's acceptable is always "now". I've heard things like that much longer than 25 years. And pretty much every one of your quotes was true when spoken (except the one about Gates -- read on). To assume they meant "FOREVER" is incredibly naive. And *OH*, 640k enough for everyone? Gates never said that. Here's him on that quote:
Gates: "I've said some stupid things and some wrong things, but not that. No one involved in computers would ever say that a certain amount of memory is enough for all time."
You: "I have been online through 28.8k modem, 64k ISDN, and onwards."
I started with a 300 baud acoustic modem. I later ran a BBS at 110/300/450 baud (110 baud to support TTS devices -- my deaf users loved it). Not sure how your "creds" matter in this discussion, but OK.
Revisit the "now" in 10/15 years. Things like starlink would be very fast to deploy today, and upgrade later. Hell, Alaska had a data cable cut by accident last year (by "A", I mean "THE" -- most of alaska was internet dark and phone service dark). A few towns deployed a few starlink nodes to cover service during the outage. It wasn't great (was over-shared), but it was worlds better than zero service. I was in one of those towns during the outage.
starlink requires no real local infrastructure -- which means upgrading would be as easy as replacing the ground hardward -- which is fairly simple. In a disaster, you would want to be in a starlink area -- at least as connectivity is concerned. Cell coverage would be spotty (or dead). Service providers would easily be hit hard. Starlink is more resilient to that.
Here's another thought: You don't break the bank giving the latest and greatest communication technology (which also reads as the most expensive) away for free. And since the "town" likely cant afford to pay those last miles of service, you give "good enough" for free. Then revisit as needed. There's a reason why fiber exists where it exists -- because there's a population there large enough to spread the costs across the entire service area.
