If a T-shirt costs $50 now, that same T-shirt might well cost $150 in a "far future" thanks to Mr Bernanke and his Printing Press (tm). (Though this isn't a certainty, merely a likelihood.)
Most bitcoin-accepting retailers still peg their prices in fiat (thus the BTC price to pay will fluctuate with the exchange rate) but in future we may well see more sellers setting prices purely in BTC terms, e.g. selling a T-shirt for BTC2 (or in a "far future" scenario, maybe BTC0,002!
) regardless of the BTC/$ exchange rate, just like a train ride between, say, Zürich and Geneva, set in Swiss francs, will cost any foreign visitor (assuming not in possession of any railcard) an arm and a leg, almost regardless of the exchange rate. (In fact, that applies to almost everything in Switzerland: very expensive, end of. )
