Yes, it has effects on the real economy (although in the case of these high-value positional goods I'd argue they're rather smaller than you might think - as likely both buyer and sellers are simply swapping for money which otherwise will sit in a bank account so the effects are limited to those imparted by the middle-men). My point was, the economy is not a zero-sum game.
