The exchange value is the speculation that you can get something of intrinscic value in exchange. So money has the exchange value, which is fully speculative. So the if's and but's above is completely rational. If I can buy food tomorrow, what if I can not buy food tomorrow, possibly I can get only something that I don't fancy. Anywy, I speculate that I can get what I want tomorrow, therefore I keep some money for tomorrow, in stead of stuffing my refrigerator with something that can degrade, or what I maybe don't fancy tomorrow. Things with intrinsic value is good, but it depends on the circumstances, maybe what is valuable today is not so tomorrow. Therefore I keep something that is not directly useful, but pure value, for tomorrow.
I don't understand what you are talking about. If you mean that money has value since it has utility in allowing an individual to choose what to buy and what not to buy, today or tomorrow, this still fails the marginal utility test (since this value is also subjective). You will have to overcome this (which you evidently shrink from, despite my insistence), otherwise we should agree that this utility is not money's "intrinsic" value. You made a claim and the proof is on you..
And I'm not choosing other names, where did you get this?
Your words are nonsensical to me.
