Say if there was a large struture in a town marketplace that people could sell goods to at a price set by a village official,
and the use the village-given cash points only usable at that village, to buy other objects others put in.
mind you this would only work for inventory items, so old fashioned bartering will still get used for liftable objects.
i figure that it would allow villages of greater size to have more personal activity(and less squatters), if per say" a really nice sword was in the structure" then more work would get done by the villager in question and the village would benefit from all its workers at an almost equal rate.
just an idea, feel free to shoot it down if you find a good reason.
