Why would anyone want to convert a promising sound currency for an exponentially-printed-to-oblivion/give-inflation-to-bankers-enslave-everyone-else/no-control-over-your-money corrupt currency?
Because in the real world utility bills, financial contracts, tax obligations, etc. are paid with... Fiat money?
Your "promising sound currency" is just that, a promise which did not became reality (yet?), while your "exponentially-printed-to-oblivion/give-inflation-to-bankers-enslave-everyone-else/no-control-over-your-money corrupt currency" is what everyone in all civilized nations use to pay their debts.
