QUOTE : On the free market, then, the various names that units may have are simply definitions of units of weight. When we were "on the gold standard" before 1933, people liked to say that the "price of gold" was "fixed at twenty dollars per ounce of gold." But this was a dangerously misleading way of looking at our money. Actually, "the dollar" was defined as the name for (approximately) 1/20 of an ounce of gold. It was therefore misleading to talk about "exchange rates" of one country's currency for another. The "pound sterling" did not really "exchange" for five "dollars." The dollar was defined as 1/20 of a gold ounce, and the pound sterling was, at that time, defined as the name for 1/4 of a gold ounce, simply traded for 5/20 of a gold ounce. Clearly, such exchanges, and such a welter of names, were confusing and misleading. How they arose is shown below in the chapter on government meddling with money. In a purely free market, gold would simply be exchanged directly as "grams," grains, or ounces, and such confusing names as dollars, franc, etc., would be superfluous
