If use-value cannot be expressed quantitatively the productivity of labor (output per unit time) becomes meaningless because there is no numerator for the ratio whose denominator is quantity of labor time.
Comment Really. Commodities do not become exchangeable with one another because they have a market price. Products acquire a commodity form. The thing common to the form these products of utility acquire, is their socially necessary labor time, rather than market price. The reason is the form itself and on what basis different commodities become exchangeable for/with one another. Market price is not what makes different commodities embodying different kinds of labor and possessing different utility exchangeable. Rather, exchangeability is effected - realized, through the price form. Lastly, a product without utility cannot enter the world of exchange because no one would want it. WL.
