Roughly a year and a half ago, the Positive Liberty commentariat and I discussed what a possible return to commodity money might look like.
For reasons unknown, these comments have since disappeared: I have a top-level post referencing the discussion in another post, but this second post has no comments at all.
Now, whenever a commenter writes something to me, I tend strongly to remember it. And as much as a year and a half later, I may want to reference it. So whatever is going on is unacceptable. Can any more technically adept readers help me?
In any case, a commenter made the following arguments, which I am going to have to summarize from memory, as they are quite relevant to a discussion of Mises' Theory of Money and Credit.
We can't possibly go back to a gold standard. Here are the reasons why:
1. Serious difficulties would arise in industries requiring gold. These are not limited to jewelry, which would vanish, but also high-tech communications and electronics, which would likewise become too expensive for the average person's budget.
2. The U.S. government could never afford to buy enough gold to cover every U.S. dollar now in circulation. Doing so would entirely wreck the American economy, to say nothing of the rest of the world.
3. There is so much economic activity, and so much economic value, that using gold to mediate all of our exchanges would make for prohibitively small currency units. Even at current gold prices -- that is, before the multi-trillion dollar gold grab needed to return to a gold standard -- one U.S. dollar would be less than 1/500th of a troy ounce.
Was he right? Personally, I find 1) unconvincing. I find 2) serious enough now, that it seems plain to me a government cannot be the entity to return us to a commodity money. I am inclined to find 3) a technicality; flakes of gold can easily be encased in a larger substrate that would make them the mechanical equivalent of coins. (Or could they even be integrated into paper money?)
Consider the following as you answer the above challenges:
A) We might easily pick another commodity to serve as our commodity currency; gold is by no means the only choice.
B) "We" in the above sentence should almost certainly not be the government; if a true commodity currency were to re-emerge, it could well be through a process of market selection among bartered goods, as Mises sketches in TM&C Part 1 chapter 2 section 2:
Now all goods are not equally marketable. While there is only a limited and occasional demand for certain goods, that for others is more general and constant. Consequently, those who bring goods of the first kind to market in order to exchange them for goods that they need themselves have as a rule a smaller prospect of success than those who offer goods of the second kind. If, however, they exchange their relatively unmarketable goods for such as are more marketable, they will get a step nearer to their goal and may hope to reach it more surely and economically than if they had restricted themselves to direct exchange.
It was in this way that those goods that were originally the most marketable became common media of exchange; that is, goods into which all sellers of other goods first converted their wares and which it paid every would-be buyer of any other commodity to acquire first. And as soon as those commodities that were relatively most marketable had become common media of exchange, there was an increase in the difference between their marketability and that of all other commodities, and this in its turn further strengthened and broadened their position as media of exchange.
Thus the requirements of the market have gradually led to the selection of certain commodities as common media of exchange. The group of commodities from which these were drawn was originally large, and differed from country to country; but it has more and more contracted. Whenever a direct exchange seemed out of the question, each of the parties to a transaction would naturally endeavor to exchange his superfluous commodities, not merely for more marketable commodities in general, but for the most marketable commodities; and among these again he would naturally prefer whichever particular commodity was the most marketable of all. The greater the marketability of the goods first acquired in indirect exchange, the greater would be the prospect of being able to reach the ultimate objective without further maneuvering. Thus there would be an inevitable tendency for the less marketable of the series of goods used as media of exchange to be one by one rejected until at last only a single commodity remained, which was universally employed as a medium of exchange; in a word, money.
