So it's about the mob mentality and if everyone is saying left is right then well.. it is. If everyone is brainwashed by fiat then unbrainwashing everyone is going to be a very difficult task if that's what its going to take for BTC to succeed.
It doesn't take that. That will happen because we will be successful and they will follow our lead (assuming that we maintain the technology and solve whatever hurdles we encounter). However, I have to take issue with your analogy to left and right. Left and right are conventions born of agreeing on labels for handedness. We are free to swap the labels and confuse everyone except those in the know. Fiat isn't like that. Legal tender laws and other government interference actually damage the cooperative human behavior that makes economies work. We are free to abandon it, but we have to see a clear path, and that is why I bring up the brainwashing. Being fully aware of the difference between left and right makes it clear that "if everyone says left is right then well.. it is." This is NOT the case with everyone saying bitcoin has value (only) in terms of fiat currencies, except on the superficial level of their superficial understanding.
Erik's blog explains it better than I have.
That aside, your question is too tempting not to answer. Without using fiat or btc I'd say an hour of my time in food is worth a fast food combo meal, pack of smokes and one day stay at a 1 star motel.
You're on the right track now. Oddly, the effect of this will be to reduce the excitement and exhilaration of watching the price of bitcoin rise. We just won't care as it becomes more and more useful in trading for such things as hours of our time, fast food, smokes, or a room.
