Use Value

Interesting question. Since use-value is, as you mentioned, solidified when it becomes used by people, wouldn't it be impossible and unnecessary to put a universal price tag on it? In other words, sense of need and necessity is such a subjective and personal concept that use value, too, cannot be objectively measured or framed.

yes the term use value is only functional when it is useful as a commodity and consumed. It is all about the usefulness of something in order to have useful and it doesn't determine price because it is just the idea that if you can benefit from the commodity, you can't put a price on it.
