You know, I really want to believe that the kind of people that would dump 14K on such pieces of wood, are those people that have amassed a large number of Bitcoins when they were like $16 a piece.
My guess is that they run a major Bitcoin business, and it would seem weird to cash out 14k of digital money, with no records of obtaining it, since Bitcoin is anonymous. Also, there would be taxes. So instead, they just buy art or something else with their BTC.
