Basic law of free market economics, for example? Demand creates supply, establishes pricing mechanism, fosters competition, etc. On the other hand, one can establish a regulated market and assign prices based on views and preferences of the regulated majority, as determined by the pricing commission. In that case, for example, TI prices will not exceed $134.95, and Wapis will not exceed $14.95, and selling Gold Dollars will be prohibited because of complaints about inferior quality.
