That's the point of this thread though.
It only makes sense to spend your BTC on goods and services if it isn't a losing investment. Right now no one really wants to use BTCs because the value is growing too fast. As soon as the value stops climbing, the altruistic crowd will buy goods and services, while the MAJORITY will sell to make their profit and leave the market.
This will be a good lesson in economics (and psychology) for all those who are heavily invested in this idea. People will make a profit, yes, but the currency will lose all appeal.
