If I answer you no then I'll be lying. Even though my hope is for us to see 1 btc equivalent to 1 btc some day with the price of fiat mean nothing to us, the current movement of the price still gives us the indication in how well accepted btc is and its demand. I do agree with your reasoning but until the I will still closely follow the btc price movement.
This says a lot. As many people look at it as currency, the price is too mainstream. And as I can see many people also invest in bitcoin, so the price is extremely important. I believe many people was attracted to bitcoin due to its increasing price, (it varies and depends tho). We don't know in the future but when bitcoin's price failed I think there are people who'll surely quit.
