Neat academic toy - unless you can predict why a large-scale, long-term internet outage should happen.

Aside from that, most of what your concept includes (but uses Internet instead of BT) exists with Nostr+Lightning.

There have been incidents where governments disabled routing to specific services or the Internet entirely to hinder demonstrations.

to give a example: https://en.m.wikipedia.org/wiki/2019%E2%80%932021_Jammu_and_...

i'm not sure if in this case "only" the 4G network was shut off, but IMO it still serves as a good reminder of when such an event might happen again.

That is why I added "large-scale" and "long-term"

How relevant is this in the context of the mesh networks under discussion?

How resilient are those protocols to attacks on the integrity of the network, when most (or signicant part) of the nodes are controlled by a bad actor and deliberately operate in a mode that prevents the functioning of the network?
