I think you have to back up a step in your idea of “value”. What makes the loaf worth $1 if you sell it for $0.99? Why isn’t it worth $1M (to a theoretical starving rich person) and you’re giving away HUGE amounts? Why isn’t it worth $0.10 and the buyers gave you $890 in charity?
A thing’s value is relative—different to every participant. And the relative values are only known (actually, not—they’re bounded above by the seller and below by the buyer) by the transaction.
