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.
The price matters the most, the higher the value of it the more people who will be convinced to get 1 of it as an investment. Btc is one of the good start on investing money, the value of it is rising day by day. And in the near future the little money you invest might be a bigger one.
