@Rick, I wanted to reply to some of your statements.
I disagree wholeheartedly with your understanding of the “purpose” of a monetary system. The purpose is one of convenience. Indirect exchange reduces the friction in an economy. I no longer have to find someone who has a good I wants AND simultaneously wants a good I have. In addition, I don’t have to continue looking even further to find someone who not only fits that condition, but also is willing to exchange with me for quantities I’m willing to exchange for.
But never forget that both sides of any exchange are value for value. Value is subjectively determined. It’s based on what use I see for the good or service I’m getting in exchange for my good or service. In a voluntary exchange, I necessarily prefer what I’m getting over what I’m giving.
Indirect exchange, involves getting a good I don’t intend to use directly, but which I expect to be able to exchange for another good or service.
Wealth is hard to quantify, but it’s “things that have value”. Creating a new good creates wealth. Money isn’t used to “represent it”. Though we may represent it in an accounting book by current expected market “prices”. In this case money is used as an accounting tool, it’s used to quantify the assets one has, as a means of comparing it to other value.
But the “money” is it’s own product in the market with it’s own value. In your car example, you completely misunderstand that the price, which you say as “worth $20,000 on the market” is based on what it might sell for if you sold it. There’s no guarantee of that value. Nor is there a guarantee you’ll get that value in the future.
“Isn’t the objective to have the money in circulation = what the car is worth?” NO! What’s the car worth? You’ve stated it, but you’ve ignored how it gets a value that’s quantifiable. It’s the expected use by someone who’s willing to pay for it. That is a dynamic, subjectively determined quantity of money. Supply and Demand determine what the price is.
Stable prices are not a goal, stable prices tell us nothing. Unless they tell us something ;). Prices are information. They represent all the various pressures on supply and demand in the global economy that get rolled up into one number that’s convenient for calculation.
Now increasing the money supply (without changing the demand for money) will increase prices across the board. But an increase in prices for a specific good would normally mean that there’s an increase in demand for the product. The problem therefore with increasing the money supply is that it sends confusing and distorted signals to the market, making economic calculation even more difficult than it already is.
Now, let’s focus in on money supply directly. Lets say that there are 200,000 tons of Gold in the world. Now let’s also say that there are 150,000 tons being held as a store of value (Saved). This means that only 50k tons of gold are actively participating in the formation of prices. HOWEVER, as prices drop, the desire to store gold will drop and the desire to get cheaper goods and services in return will rise. This will draw more gold out of savings and into the market to compete for goods. Thus driving prices back down. That’s the natural that prices have on the “money supply”. As prices fall for goods, and more so as technology advances, it will become more and more “profitable” to engage in productive efforts that “create gold”, i.e. mining. This will contribute a relatively stable inflation of the money supply ALSO. But “creating gold” will always require capital investment of time, energy, and goods. It cannot be done in a vacuum.
In the above example, let’s talk about interest rates. Some people will save money to spend on their immediate consumption, think of this like your checking account. This type of savings would actually incur a penalty (think of as negative interest) because storing, auditing, and transfering gold, as you engage in your daily transactions would be a service which would be charged for.
However, interest rates operating on market principles would have the effect of drawing gold from savings into longer term investments. If I were running an investment bank as detailed above, I would have two rates. One that I loan at (12%) and one that I pay at (10%). I would use the 2% difference to cover my storage, auditing, collection and accounting fees, and to pay for insurance to cover the inevitable losses. There would be a ton of interesting ways to structure this type of investment banking. In fact our markets show us how these things play out.
But the mistake is to forget that money is it’s own commodity, NOT a trick of accounting that represents value, but a commodity that has it’s own inherent value AS WELL AS value in it’s use for indirect exchange.
