As flawed as our current system is, the dependency of most everyone on fiat cannot be denied. It's hard to imagine living a day without using fiat for our daily transactions. Bitcoin, or any other crypto currency for that matter, cannot simply replace it right now. If another financial crisis happens, let us see what bitcoin's role will be and how it is going to affect its price.
Whaever happens, as long as the money is unchanged, and the cycle of money continues, we have no choice but to use it and believe in it. We can't say that we are not believing in fiat when in fact we are using it and we are part of the system (government). In short whatever the government give us, we should accept it, or go and try barter, if you could find one that wants to exchange their goods to yours, or worst, die in hunger.
Using doesn't mean believing
How many people are earnestly believing in HYIPs or ICOs? I don't think many, but people are still pouring their hard earned money into them. How come? Just because they want to get profits even if they are fully aware of the risks associated with such "investments". I guess with fiat it is basically along the same lines. You have to use fiat to buy food and pay taxes. Ironically, you may use it to earn even more of it, but this doesn't necessarily mean that you should believe in it
