I think the financial reality of many economies limits the usefulness of what you can do with currencies. Just because you have your own currency does not mean you can maintain it without a peg and that peg comes with a cost. And then there is the political will. The British Pound for instance should have allowed the UK to fare much better than the Euro-Zone during the energy crisis, but it really did not.
