Referenda that have a profound impact on your system of government should be rare. There is an impact on both economies in terms of investment and planning. They should be offered in a once in a generation basis. Many (most?) countries have constitutions that forbid splitting up the country. UK is pretty unusual in providing for a referendum of the type that happened in 2014.
