Use-value (n.) is grounded in the idea that nothing can have value without being an object of utility.
Use-value (n.) is value on account of usefulness, regardless of whether it is produced through labor or is natural like water and air.
Use-value (n.) keeps no memory of who made it: you cannot taste in wheat whether a serf, a peasant or a capitalist raised it.
Use-value (n.) is no 'logical' concept just because man must always eat: by that reasoning breathing would be a logical concept and not a physiological one.
Use-value (n.) is greater in the consumer's hands only because it is realized there — but no one pays for a commodity twice, once for its exchange-value and again for its use.
