Having a back-up plan is nice, but focus on building the network (of people) first, then the mesh (of LoRa devices).

I was thinking the same thing.
The problem with these lora implementations is how easy it is to disrupt them.
Meshtastic is one of the larger ones and it floods it's own network with interference from poorly set rules in the protocol.
It doesn't help that 915mhz is in a range that often only allows 1w devices. These radios are simply too weak to be used in a serious scenario where state actors can disrupt the frequency.
Reticulum seems nice especially because it can be used in the lower frequencies which will allow for much longer range communication. And a lot of those devices for say 20m can operate up to 1500w. Which while still easy to interfere will be more resilient than a typical lora device.
Lora to me best serves as a very contained way to interact locally (within a few km) with a handful of people.
Any large network would not be hard to compromise I imagine all it would take is finding one device using as a router for a private channel. And there is instant access.
Reticulum may be more secure than meshtastic which is what I am more familiar with but I don't know to what degreex
