Ostentation-Value and Fame

For Smith, the "paradox of value" illustrates the distinction between Exchange-Value and Use-Value, which he resolves by reference to Labor-Value, i. e. that diamonds, which have less Use-Value than does water, have greater Exchange-Value than does the latter because of its greater Labor-Value.  However, that reduction does not seem to explain the exorbitant amounts paid for celebrity memorabilia--signatures, clothing, toilets, etc.  Nor, even if it is a factor in these transactions, does their relative scarcity, since the same possessions of unknown people, when not thrown away, usually fetch nothing in exchange.  So, plainly fame is the primary attraction of such items.  Or, in other words, their Exchange-Value is determined by their Ostentation-Value.
