100% - value is not based on production costs.
Gold has value to you because you say it does, not because of some inherent or intrinsic value. The reason that you have so valued it may be because of certain intrinsic *properties*, but it has no value until you attribute value to it--and, in so doing, you have attributed value to it...by fiat (by decree).
Bitcoin has value to me because I say it does, not because of some inherent or intrinsic value. The reason I have so valued it is because of certain intrinsic *properties*, but it has no value until I attribute value to it--and, in so doing, I have attributed value to it...by fiat (by decree).
I am 100% on board with Ammous' book _The Fiat Standard_ in which he uses the term "fiat" to mean, basically, fraudulent. Our fiat/FRS is fraudulent, but if by "fiat" we mean only "attributing value to something" then everything is fiat--valued subjectively and on the margin.
