The debate about Scottish independence and its currency is a sideshow. Has Singapore, Ireland, Slovakia, the Czech Republic, East Timor, Eritrea, South Sudan, Taiwan, Estonia, Ukraine failed or succeeded because of currency issues? They have not. Separating nations will produce tears, challenges — often bloodshed, and the result could be good or bad. But currency is not an issue. By banging on about it the Better Together Campaign (which I support) shows how removed it is from the grass roots sentiments that move people towards independence. And its difficult to understand the Bank of England Governor Mark Carney stating that for a currency union to work there has to be common taxation and spending and that it would be incompatible with sovereignty. If that were the case the Euro would never have happened.
