I’ve thought about something like this before, but in slightly different context. There would be a new item, a key, which would be created while facing the door to give that key permission to open that door. A player could set up a toll gate, along one of the main roads, to help with road upkeep. While *crossing fingers* we do not have any major road destroying trolls right now, that’s always a problem. Near the gate, would be a shop selling keys to that door for 10 stone, then they would have access to passing that toll gate door with their key for a week before the door would be reset, causing all keys to be invalid so people would buy more keys for more stone. The stone recieved from the keys being bought would go towards the upkeep of the roads, and as a community you could easily raise good amounts of stone to help with road repairs. Hope you guys like this idea!
