 Unfortunately, this argument from function falls short of providing a basis for the use-per-need view. The function of food processors is to meet food processing needs, but no one believes that willingness to pay for food processors is an inappropriate basis for distributing them and that we must do so in proportion to the presence of vegetable-slicing needs in the population. The problem here is that meeting some needs, but not others, matters as a concern of justice or equity. In the next section, we shall return to seek more persuasive foundations for the use-per-need view.
