The
US is a USD 13 trillion economy. I don't think there is USD 13 trillion
of available gold to purchase in all the world. And if there were, with
what kind of money is the Government going to purchase it? With dollars
created out of thin air? You'll run into a hyperinfalion worse than
Weimar.
So, to begin with, you cannot get the physical gold.
Even
if you had it, the 13 trillion dollar US economy grows at a potential 3
to 3.5% per year. New gold dug out from the ground is much less in
dollar terms than that. So you'll end up with a deflation if you run on
a gold standard.
The fundamental error with this argument is that the dollar cannot be defined as both a weight of gold and a Federal Reserve Note. If gold were to replace federal reserve notes, it doesn't
matter how much gold or federal reserve notes there are, only the ratio
between the two. This will give an exchange rate (and this is why gold prices go up as the ratio of supply between the two changes - and also why all attempts to peg FRN's to gold weights have failed).
Money is only valuable in what it can be exchanged for. If gold replaces federal reserve notes as money, there should be no difference in the exchange rates between 2 different goods using gold as an intermediary as opposed to using federal reserve notes. In terms of real goods and services, the total value of the total American gold supply (not already put to consumer use) would be equal to the total value of all federal reserve notes in circulation.
FINALLY, "dollars" tells us little about actual value. It is a nominal term, not a real term. 13
trillion dollars sounds like a lot, but what does it mean? You have to
judge value by comparing the desire for one good in terms of other
goods. Money is supposed to serve as a master exchange rate, whereby
other exchange rates can be determined by looking at both their prices
(or exchange rates in money terms). If we redefine the dollar to mean
1,000 ounces of gold, the real value of our economy won't suddenly shrink by 1,000,000
times, although in nominal terms it would. Prices would simply change, in nominal dollar terms, to reflect the real values of the products, by way of their exchange ratios with other products.
If nominal and real value are one and the same, we could argue that any type of inflationary scheme, including hyperinflation, is a
great thing, because it greatly increases prices, which increases our
estimation of GDP in nominal (and thus) terms. Yet if compare the output of real
goods and services in a hyperinflation economy to a sound money
economy, we will probably discover a much easier facilitation of trade
and thus more output in the sound money economy.
Furthermore, there doesn't need to be the same amount of money in circulation as the monetary value of all the goods produced in a year.
This only presents a problem if for some reason everyone had to trade everything at the same time...or if someone wanted to buy the productive output of the entire annual economy in a single transaction.
Consider a bank loan of $1,000 with a fixed monthly fee for this loan of $50 until fully repaid. If the $1,000 loaned is the only money in existence, it seems you can't pay back the $50 interest fees. This is false, however. If you pay the bank the first $50 out of the $1,000, then you can bury the remaining $950 and still make every monthly payment. All you have to do is exchange labor for $50 every month. Whether you directly labor for the bank, or you labor for those who the bank also finances doesn't matter. The end result is the same, which is that one small amount of money can be repeatedly exchanged for products whose total wealth that far exceeds this amount.
Deflation in consumer prices without deflation in wage rates is the best possible thing for any economy. It is comparable to wage rates going up with consumer prices remaining stable, which is similar to what is currently happening (although apparently not for too much longer).
