Andrew (K), doesn't Fred argue in detail that in Marx's derivation of prices of production he does not take the physical conditions of production as given? Aren't you in your example here assuming the very point of dualistic point of view which you and/or your cowriter (Alan F, Alejandro or Chris Burford) has criticized, i.e., you begin with a price-free physical system and then try to map it out into a price (of production) system? Yours, Rakesh
