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.

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.
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?
