Bradley in DC, I want to continue to argue that gold is a type of fiat money, fiat meaning we put "faith" in that it will be accepted as a unit of stored value in exchange for actual commodities that we consume while having little consumption value itself, other than as jewelry. It's scarcity and present impossibility to "counterfeit" makes it an excellent fiat currency. However:
1. The "Gold Supply" constantly grows through mining by the tens or hundreds of tons per year. New gold enters in private hands so its entry into the marketplace is already inherantly unfair to the general public. In effect, wealth was created without having to produce value to the community, in a similar way as printing paper money on a machine, though more labor intensive.
2. By its nature, using gold and silver as money has produced a long history of slavery, war, theft and other atrocities as there is tremendous incentive by those who are prone to violence to go straight for the gold & silver as opposed to producing goods and services that have tangible value to the community.
3. The fair distribution of gold, or money backed by gold, is rarely talked about by gold money advocates. It's an easy system for Americans to promote as they have (once had?) enormous gold stores, not all of it acquired ethically. What about countries that have no gold? Most of the above ground gold is in the hands of elite private citizens or heavily armed 1st world nations.
4. Gold does not fairly represent the goods and services exchanged for it, because gold lasts forever and food, consumer goods, etc. last for days, weeks and/or decades. I believe it was Silvio Gessell who points out that true neutral money must fall in value to best mimic the underlying goods and services.
5. Gold money does not address the problem caused by the growing gap between national production and national income due to automation. We don't earn enough to pay for the goods and services that we've produced. This falls into the realm of National Dividend, Basic Income Guarantees and, I believe, the work of Henry George.
Sorry to go on at length. I'm not trying to be a know-it-all, as I am just learning all this in the past year and think that all ideas should be on the table and that we should equally discuss the flaws of using gold as money as we do its strengths.
Joe, it's good to see discussions of important public policy issues! You define your own terms (fiat money) in a manner contradictory to the conventionally accepted one. Fiat money is paper money that is not backed (redeemable) in an underlying commody. Commodity money (such as gold or silver) cannot be fiat money. One could have paper instruments (such as gold certificates) that are redeemable in gold and would not be considered fiat money, but there are, by definition, no commodities that are fiat money.
Without wanting to come off as pedantic, I'd like to suggest some fundamental readings:
The last chapter of the Princples of Economics by Carl Menger on how money evolved in the first place (and what money is). He has a similar article here:
http://www.mises.org/web/2692
The Foundation for the Advancement of Monetary Education (FAME) has lots of good resources:
http://fame.org/ReadingList.asp
The Committee for Monetary Reform and Education
http://cmre.org/
The Mises Institute has a lot of good information including a pdf of a book of Dr. Paul's
http://www.mises.org/books/goldpeace.pdf
In response to some of your observations:
1. Yes, new gold is mined. This introduction into the community is inherently "fair" even by your subjective definition since they mined the gold and produced something of value.
2. "By its nature" no such thing.

If you argue one does things for money, it is the nature of greed for money itself, not the nature gold and silver.
3. "Fair distribution" is an alien concept not applicable here.

If you understand what money is and how gold evolved in the market (ie, how
people choose gold over every other competing monetary instrument), it would be a better discussion. Check Menger. It was FDR (out of "fairness" I'm sure) who confiscated monetary gold held by the common citizens now held by a heavily armed elite that offends Dr. Paul and his followers.
4. If one didn't find the exchange "fair" or to their advantage, the exchange would not take place. How often do you give up your labor when you do not subjectively "get your money's worth" out of it? Don't some things, in fact, increase in value over time? I'm not familiar with that author, but that presentation of his ideas gives me little inclination to spend my time that way.
5. If prices are allowed to fluctuate in a free market, and automation reduces relative prices on those goods, the prices gently fall over time to the benefit of consumers (think of Walmarts falling prices ads).
I think you are trying to address concerns that go beyond the nature of money. A more focuses line of inquiry might help in a conversation on a forum like this one.
