In the Radford POW camp scenario, cigarettes had emerged as a form of money. They were being used for transactions as well as consumption.
--
The system that emerged in the POW camp was just, and the distribution was also fair. The reason is:
--
A "just" price for a good is where the marginal utility from the good equals the last dollar spent on that good.
From another viewpoint, a "just" price is where the price accurately reflects the cost of production.
Buyers should be willing to buy and sellers should be willing to sell.
--
The pricing system emerged from within the camp itself, and incorporated the mutual agreements of all the prisoners.
Such a system should not be regulated, and no further intervention is necessary.
The system itself will evolve and guide the market towards equilibrium. This is the essence of a free market.
