ABSTRACT
Goods, whose values have been minimized, are those whose marginal benefit is close to zero. Well, the transition from a small marginal benefit to zero benefit is apparently a smooth one, not a sudden jump. In the same way, the boundary between free and commercial goods is also a fluid one. Actually, in the modern functions theory first the boundaries between those the function exist are analyzed before the function itself is being looked at. It is always just intervals in which people move around. While in the older economics vagueness and ambiguity of the term value created difficulties, which are very well-known by the beginners and which have not been overcome, the newer economics is in danger of creating misunderstandings in a different area, which are no less irritating and annoying and which have led to many obscurities.
