You are obviusly not stupid, and yes, the value is defined not by the beer in itself, but individuals, considering it, all persons are different, so there is no yardstick, it is personal, psychological, individual. Every price you see, is the value from individuals preferring, with the help of their total life experience and individual needs, one thing over another. Is this your problem, do you think that therefore, we can not group value into two distinct types, intrinsic and speculative?
Oh, we can have many groups of value. In fact, I would say that intrinsic and speculative would surely not be enough since, in my book, intrinsic value would be an empty set. Speculative is a subset of extrinsic value since one might value something not merely because one hopes to exchange it for increased value/price later.
Now, the intrinsic properties of gold might have subjective value in the common sphere. It is shiny, resists corrosion, easily malleable, heavy (dense), all that jazz. But all those are location, time and context dependent.
At this stage, I think we both see where the other is coming from so there's little point beating it to death and there are many better places to read about the arguments. Austrian economics just tends to reject the idea of intrinsic value.
https://en.wikipedia.org/wiki/Subjective_theory_of_valueAgain, you seem to be fixed on the word subjective, as if it under discussion. Who talks about objective value? Not me. Your struggle with the word intrinsic, is as if you are hypnotized, and programmed to go into delirium mode when the word intrinsic is uttered.
Well your attitude is not helpful. It is destructive. It is a barrier to learning a meaningful aspect of money.
And no, there are no better places for this discussion. This is the best place.
