From what I have seen so far in this forum and other crypto platforms, most of us want fiat eliminated. But let us not forget that there are still situations whereby we can't use crypto except fiat like in rural places without computers or even internet facilities.
Oh well you look so cute while saying this 
. So innocent who thinks that we all are walking tomorrow morning towards the President's house and giving our dissent to Fiat forever. Chill Bro don't freak out. No one is going to eliminate fiat in near future. Forget rural, even the urban crowd doesn't knows completely about cryptocurrencies and its usage. Even if everybody gathers around knowledge of BTC. It's hard thinking that we have no fiats because that would be a day when we are also completely forgetting our governments because they are in political supremacy because they can control the finance of their country. Without that they are just puppet ready to be overthrown.
