Thats what helium and some iot manufacturers tried like Ring. A mesh that only routes out the least utilized egress node.
This is also convenient for backpackers and campers to request help, or get alerts, with their exact location
Meshtastic is actually good though. Helium is just another crypto pyramid scheme that pollutes the airwaves. The things network is a much better alternative from people that actually care about making a great network and not about getting rich fast.
