I agree with the whole property-rights thing being necessary for a larger city to work in the game. If you run out of room to store your stuff on your own plot of land, and you just break into your neighbor's house and start dumping off your junk and taking their stuff, obviously that's not very cool
Keeping things on a free market kind of footing is a great idea, where you can have a sort of real-estate market for pre-determined lot sizes.Maybe a loose system of tributes/taxes could be set up to build up a public fund of valuable materials or metals for trading and working up towards better weapons and armor for hunting, policing, and defense?
At any rate, i'd be glad to lend a hand with the building of a city after the hearth-pocalypse. Not sure if I'd want to be a resident and live the "city-life" myself, but i'll gladly be a useful suburbanite commuter
), i will help the New Brodgar is sorta-kinda-in-a-small-way inspired get started, then leave to set up my awesome militaristic trade empire! 
so you can count on me being there, at least for the first few days.
