I have no "angle". I am trying to explain that there is a definite value associated with a commodity that can be quantitatively measured.I said the price of an orange always reflects the labor value in it. I said that there are other factors that also affect the price of an orange. You need to stop misrepresenting what I am saying.You claim that sometimes the price of an orange reflects the labor value put into it, and sometimes it doesn't. How do you know when it does and when it doesn't? If you have 10 farmers, one has a cost of $0.90/lb for his oranges. The next has a cost of $1.10/lb. $1.20/lb for the next. And so on and so on. So what is the value of an orange? The fact is there is no way to tell. No matter what the cost for each farmer is, all the oranges sell for the same price for the same quality and size of oranges. That's the market price.
Market price is determined by supply and demand. If supply and demand are in equilibrium then that is the closest that the market price would get to the intrinsic value of producing the orange.
How Demand and Supply Determine Market Price
I can go out in my yard and cut down a tree, mill the wood, build a piece of furniture. If that piece of furniture is of use to someone else and I wish to exchange with them for something they have likewise built from their own labor then the exchange rate would be comparably based on the value of the labor.
If instead I decide to sell the furniture on the open market then the value that was created from improving a fallen tree is subject to forces outside of my control. But this in no way detracts from the fact that I created value by improving the fallen tree using only my labor. If not for my labor there would be nothing of use to exchange and has to be reflected in the price.
Why is it important? I mean, there's a reason you want to inject the concept of "intrinsic value", right? What's your angle?
But why is that important? What do you propose to do with this "definite value"?
