As I said, if you are in a such remote area that you can't even run a mobile LN node like Breez, Blixt, SBW, Nayuta, Electrum... I don't know why do you want to complicate so much. If you are in a such remote area, you will not have anyway where to spend your bitcoins, not even online. You will be more focused on shelter, water, food, security than... internet and bitcoin.
Again, thank you for your reply.

It is not a thought experiment about a node being in a remote area. To the contrary. It is a thought experiment about where exactly the "edge" of the network even is, whether we can safely push lightning and lightning payments out to the edge.
But I suppose I did not spell it out that way and can understand how you interpreted it.
