All my points relate to the OP's original question; essentially, what is the difference between a fiat dollar and gold, and how do you reconcile an apparent equivalency, based on the unqualified assumption that both derive their value from perception?
Your initial answer, the spirit of which I agree with in principle:
Yes, both are based on perception. But, gold is based on perception in the free market. Mankind chose it as money because it is the best choice. Paper money has value because the government coerced you into accepting it as legal tender.
I agreed, but elaborated, as I question the unqualified premise that value is based
solely on perception. Government coercion is a separate value determinant, if not a complete distortion. My point speaks
not to a fallacy of composition on your part, but rather to the one given to the OP from the one he was debating: (emphasis mine)
He said that the dollar derives its value from the perception of its value. Gold (and everything else) also derives its value from the perception of its value. What is the difference between the fiat dollar and gold, since both of their values are merely a perception?
The fallacy of composition arises when one infers that something is true of the whole from the fact that it is true of some part of the whole (or even of every proper part).
Fiat money defenders commit a fallacy of composition error by considering one value determinant, while ignoring all others. Value is derived from many determinants, like:
- Quality, or perception of utility ("These apples looks healthier than the others")
- Demand ("I need some fruit!")
- Scarcity, or supply ("Gee, hardly any apples are available this time of year")
- Marginal utility ("I need exactly two apples for my recipe. A third apple is of no value to me.")
- Marginal substitution ("I love apples, but wow, look at those amazing oranges, and they're on sale!")
- Coercion ("I hate apples, but if I don't get some for Baby Cakes, I can't get no lovin')
The above list is by no means exhaustive, but not all of these are based on perception - unless we want to play super-loose with semantics and say that everything that involves the human mind is derived by perception: math, physics, anything at all. It is true, but also meaningless.
To place value into the nebulous "derived from perception" cloud is a fallacy of composition, because it is possible for an individual to perceive ZERO value to a thing, but still be forced to pay a price. Value or perception may still be involved, but it may be for something else entirely. Thus, such "value" cannot be imputed to whatever is being considered as having value.
For example, I put a gun to your head, and say, "Buy my kid's girl scout cookies." So you buy a box, but later throw the cookies away - for whatever reason - out of sheer disgust, you're a diabetic, you hate cookies, etc., - for whatever reason, the cookies are
NOT VALUED. Never were. What you valued when you paid for those cookies was not the cookies, but your life. As a compulsory medium of exchange, the cookies were incidental - so
it cannot be stated that the cookies themselves derived value from your perception. And even if you ate the cookies, the lack of marginal substitution (alternative choice) made the perception of value absolutely meaningless.
I don't consider it a waste of time to attack the entire premise of the simplistic assumption of fiat dollar defenders ("value derived solely from perception"), which I do believe is a fallacy of composition at work.
