Well their citizens have the option of using an alternative currency such as the USD or Euro or whatever if their leaders really screw up, and it doesn't seem right that you should lock out policy tools from developing countries just because the occasional despot or incompetent screws up fiscal and monetary policy. Eventually many of these countries or regions, with luck, will mature into stable states with competent civil servants that should have the full suite of tools that our civil servants use and employ. Not be locked into a limited child's toy tool set just because their predecessors were less than competent.
