That's why you can't rely on it.

If things go bad, you need to own the tech completely. Be able to setup a wifi hotspot with services that can help your community (wikipedia, openstreetmaps, low-res movies), or have pendrives with critical knowledge ready to be shared, etc.

The low power radio is more of a short term thing, for "what's going on" soon after the first moments of a crisis. Building long-term resilience is much harder.

IMHO, the loss of access to knowledge is much more detrimental than access to a network of people. One can eventually get you into the other, but there's only one you can actually own.
