What is “too far away”?

Hmm, you’re right, I guess I don’t mean the distance of the link by itself, but rather the fact that the number of hops and the dependence on central (?) high-power long-range nodes limits how far a message can go

While technically a mesh network, I’m not sure that with 3-7 hops it provides the benefits of one; in theory, just by being mesh it should be able to have a much larger (unlimited?) reach, just like the Internet.

Instead, from what I understand, user nodes are recommended to not participate in the routing, = they are just clients, but by being “mesh” they would be expected to actively participate in the network.

In this sense of “peer-to-peer”, we could say that my ISP is also a peer, and if it lost the connection to all other ISPs it could still continue working within the reach of its infrastructure, = my ISP is off-grid as well, and my connection to the ISP is independent since they own the fiber

Instead, I think the focus should be on building a distributed mesh network that is resilient and can’t be taken down by the failure of a couple of nodes. Similarly, with the dependence on LoRa radios: if e.g. the import or usage specifically of LoRa™®© chips is banned, the nodes who chose to use alternative technologies would not be affected and the network could continue to operate normally
