Interesting try but Bluetooth LE is a non-starter when talking about building a truly decentralized mesh network at scale. The range isn’t there to build a network unless its very tight (in distance). You need sub MHz and eventually cubesats to build something robust, everything else is a toy.

Using the phone's RF modem itself would be the ideal choice. Why aren't there any userspace applications over this?

Baseband access limitations. External RF/SDR solves for this if you’re seeking long haul RF capabilities, but admittedly requires non native/external hardware.
