clax, are you just going to ignore everything I typed above and repeat your argument ad nauseum? I can say the sky is purple a billion times, but that won't mean the sky becomes purple.
Maybe thinking about it from these questions will give you another take on it:
1)
Do you think gold is subject to supply and demand? And do you agree that the supply and moreso the demand changes over time? If so, you agree that it is not completely stable. If you don't agree, you are ignoring the real market price changes- actual data. You are literally ignoring fact.
2)
Do you think that money should be as stable as possible? If so, it makes no sense to let gold which goes up and down A LOT be money, at least not without central bank intervention.
3)
Do you agree that with any item in the world some people will value it more than others? Including gold? (take a father who has $10 USD to his name and has to feed his family- he isn't going to pay it to buy gold. The gold speculator on the other hand, might. If you agree, you agree that value is subjective and that goes for ALL value whether it is gold or the USD.
Honestly, please read up on the Federal Reserve system and monetary theory because I think you are misunderstanding how things work. Your implication that the Treasury is responsible for the currency, not knowing the difference between nominal and real value, etc. suggests to me you haven't familiarized yourself with the facts, theories, and system before you started arguing against it so vehemently.
Also, central banks in no way look like they are going to be switching to gold any time soon
