Those are reasons that people become willing to give up something else for it, and, as such, reasons why it has value. The value of a thing is what someone is willing to give up in exchange for it, not the reason they are willing to do so. That's just what value is.

This is in the context of a discussion of a tax on land value which is presumably a function of the monetary value placed on that land--i.e. how much someone is willing to pay for it. But, sure, pay a land value tax of 10 percent of the sheep grazing on it or whatever.
