So how do I define V4V?
V4V is voluntary exchange — each person gives something they value less in return for something they value more. Value is subjective, with no coercion and no fixed prices.
Value is a subjective judgment of an objective property which is intrinsic in the valuee regarding the utility of the property to contribute to the valuers life.
This judgment can be erroneous. Either regarding the utility of the property or the existence of that property.
