You quoted all the relevent parts of my post and completely skipped over their meaning. I said at the outset money is a medium of exchange, while diamonds are a consumer good. Money has value for what it represents, not for what it IS; diamonds are the other way around. When people trade money for goods and services the money represents the value that changed hands. It is not a valuable item in itself.
Your example of “Zimbabwean diamonds or Zimbabwean dollars” shows you really don’t understand this difference; it’s like asking which weighs more, a pound of lead or a pound of feathers. Diamonds are not money because their worth is artificially manipulated and inflated. Check out the posts by elucidator (#53), villa (#55) and Lemur866 (#60).

If diamonds are used as a medium of exchange, they are indeed money. They would not be very good money, but they can function as money nonetheless. Many “consumer goods” have been used as money: silver, gold, beads, salt, ivory, tulip bulbs, those big huge rocks with a hole in them, etc. Unlike greenbacks, diamonds are not, and could not be fiat money. That is the difference, and I suspect is the source of our misunderstanding, as you say “Money has value for what it represents, not for what it IS.”
Fiat money is very useful, but can easily fail, which is why I brought up Zimbabwe. This is also the reason some people keep a bunch of silver dollars around. I honestly don’t understand what you’re getting at with the pound of bricks v. pound of feathers analogy.
Of course I realize that the international diamond trade is manipulated, although probably less so today than 20 years ago. I even co-authored a paper on industrial organization in the diamond trade back in my grad school days. I never said diamonds were good money, but they aren’t money because, “Diamonds are not money because their worth is artificially manipulated and inflated,” as you say. Many, many, fiat currencies around the world are artificially manipulated and inflated, but they are still money. Think, “official exchange rates.” When the U.S. was on metal standards, no doubt the metals market was medaled with; does that mean our grandparents weren’t using money?

“Utility” and “enjoyment” are not synonymns, and neither are “utility” and “value.” That’s what makes diamonds a luxury good, not a necessity. The Mona Lisa is also a luxury good and always has been, as is all art that is created on commission or sold for a profit.

Utility and enjoyment are indeed the same thing in economics. (Well perceived enjoyment, if that caveat is were the disagreement lies, my apologies) This is purely definitional from any econ text, I don’t see the argument. Value is a function of aggregate utility in a market. Again, I don’t see the argument. Something without a practical use can indeed provide utility and have value, obviously.

Point 1 - I’ll repeat again: Money is not a “good”; it is a medium of exchange. Obviously it is more convenient than barter, because it was invented to replace bartering. Diamonds have none of the advantages of money, because they are not a medium of exchange, and have no universally agreed upon value.

Using the word “good” was perhaps a poor choice of words on my part. However, money has no universally agreed upon value, and I think this is where a lot of non-economists run into trouble. If money had an agreed upon value, there would be no inflation, and no currency exchanges. You may value $5 US at 1 hour of labor, where I might value it at 2.

Point 2 - This is circular logic, bordering on stating the obvious. All you’re saying is that if something useful is rare it will be worth more than something that is useless. Well, no shit. Take a walk in the desert sometimes with a pound of diamonds and a pound of water. See which one seems more useful. Of course, when you’re in the middle of a city you still need water to survive, but you don’t “need” diamonds there anymore than you did in the desert.
And that’s the point of this thread.

I don’t think we disagree here, but quite a few of my students when I was teaching had trouble with the inherent reason teachers made less then football players.
