 What emerges from the haggling is not only a deal, but something larger: a community. There was no central decision about who should produce tin, or whether anyone should; no central decision about who should consume tin, or whether anyone should; no central decision about what should be given in return for tin. All that happened is that some people guessed that if they were to produce tin and bring it to market, it would be worth something to customers—enough to make the venture worthwhile. When some of these guesses prove correct and trades are consummated, a market in tin emerges and becomes part of what brings people together as partners in mutually beneficial ventures.
