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.
I so agree with you. Aside from your reasons, their are still people in every community that are not used in using cryptos most especially the oldies who are not interested or should i say still ignorant in using technologies and lack of knowledge about the digital world because they are already contented of the kind of life that they used to have.
