Using high power to bridge vast unpopulated regions doesn’t only defeat the ethos of Meshtastic. At 900+ Mhz UHF, it flat won’t work in practice.
Yes, theoretically you could do like AT&T and erect towers to relay signals across vast open spaces, at enormous cost that nobody would fund. Or you could use tropo scatter with 10,000 watt transmitters and specialty receiver nodes to link points over the horizon, which would also be both impractically expensive and illegal.
The only (non-wired/non-internet) method that could possibly work would be either a fleet of Meshtastic relay satellites or HF radio in the shortwave spectrum.

None of those will ever happen, so might as well just tunnel traffic through the Internet and accept that for long distance communications, you’ll be stuck with whatever satellites are still operating and HF radio.

When I worked as a network tech at a local school district we’d regularly have parents come in to complain about their kid’s “allergy” to the school WiFi. Strangely their WiFi at home streaming TSN 24×7 was never an issue.

Considering there is literally nowhere on the planet that is “free” from RF energy, claims that people are sensitive to modern day radio devices are akin to someone sitting neck-deep in the ocean on a foggy day complaining that the fog is stopping them from being dry.
