If the BC marketplace cannot provide real world goods and services for BC, then it will be doomed to failure...
Some people are stuck on the idea that BC is valued at the expense for generating BC's...
BUT...
The problem is that if there is no commodity available that people want, one cannot expect to see people pay $ for BC, regardless of the cost one incurs in generating them...
It is like saying I spent $X on creating Salmon and Sauerkraut Smoothies, so people should buy it for $X, but since no one wants Salmon and Sauerkraut Smoothies, no one will buy them, most likely they will not take them for free.
OR they will buy it for $X in hope that soon enough it will cost $2X to generate them so they can run away with a quick 100% profit via selling them to someone who'll sell them for $4X. I can't get this chronic-deflating scenario out of my head, darn. I for one will easily buy $100 worth of coins and offer whatever I'm gonna sell in the future for Bitcoins also, provided that the price was approximately constant near the lowest global cost of electricity (about $3/month/CPU). Only then will I be virtually sure that I won't have problems transferring my coins out of the system for cash or vice versa at any time later, not waiting fearfully for a price bubble to pop.
