I mean you could have an open wifi mesh and/or a network of either cheap fibre/ethernet with open switches. Then using OSPF or a similar routing protocol that supports routing over LAN networks you could handle the routing between all the remote networks.
I think you'd need to break the network up at some points to break down the broadcast domains. You could do a similar thing to defederating, by not accepting certain routes, or routes from certain OSPF nodes.
Issues with LANs that get too big without splitting into a new LAN (limiting broadcast domains) and definitely even the most modern wifi becomes problematic with a number of active stations online (wifi is half duplex in operation). So multiple channels and some backbone either over point to point radio links, or cable to connect wifi zones and alternate channels would improve things somewhat.
Not sure why you'd want to do something like this. But the tech to do it is fairly inexpensive.

Check Lora Radio mesh. It’s kinda what you describe.

I’ve been interested in this for a while.
I’m in a regional area of Australia though, so can’t get a connection out here.
