Fiat is needed to measure the value of bitcoin so it cannot stand alone as it is depended on it
Fiat is needed to measure the value of gold too
And a lot of other things as well, in fact, almost all things. But does it mean that gold and other things have no value without fiat? Since it is obvious that weight can perfectly well exist without scales, it should be as clear as day that fiat serves only a utilitarian function of revealing the value of one good against another good (but not creating this value, which is inherent to things). So are you going to continue claiming that Bitcoin can't stand alone even if that would mean that all other things couldn't have value on their own either, i.e. without fiat hanging around?
