“Though I know no cs, I can tell that your reasoning is deeply within the context of a capitalist economy.”
Actually, it’s from the perspective of pure exchange. So, we could be talking about tribal societies using skins, foods, and jewelry to trade or talking about a market index, but the nature of the exchange is a given regardless of formal theory/narrative. When you drop the assumptions of Marxism or any other school of thought, you get to see the nature of how a person may or may not consider an exchange (should I exchange? is this valuable to me? Do I want to give up X for Y?). When trying to figure out when to make a good available to trade for that of another (be it money or another good as commodity), these aren’t computable for the very reason I’ve been pointing out in every post (these valuations are based on whether or not one is willing to consume it or not [marginal utility]). No where have you come to the argument with a coherent refutation or replacement for marginal utility, so I have no reason to accept your position sans marginal utility.
