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.
True, the price of bitcoin indicates how does bitcoin perform in a certain period of time, it shows how does the people here become productive , the substantial outcome with the help of each one of us, it will give you a bigger amount of profit and thats the reason why people hold bitcoin, they want a bigger amount of profit.
