Value is not subjective. It is objective. A foodstuff is valuable as nourishment, because it has the objective potential to nourish a human person. The value of a strawberry may not be accessible to someone with a strawberry allergy, but it maintains that value.

Where the organization of labor and ownership are concerned, there may very well exist various legitimate ways to do so, conditioned by circumstance and constrained by basic objective moral principles (like justice). The value such arrangements provide to various parties may differ.
