I see two different philosophical inspirations behind Benetti-Cartelier’s study. Marx: Political Economy holds back and contains the monetary approach of society and this is an unfortunate mistake, and Wittgenstein: Political Economy in general and the law of value in particular are confused and useless, which can be corrected by rigorous analysis under monetary nominalism. But it seems to me that the credibility of these two ideas is undermined by their combination rather than bolstered. One should choose: either the advantages of nominalist analysis but without Marx’s moral indictment of the monetary or mercantilist economy; or the inevitable approximation of moral realism but without the advantages of Wittgenstein’s inspiration.
