If Scotland were to vote for independence, it would face a whole host of problems. Would it have an army? An intelligence service? Both would have to be established. A tax collection agency? A financial regulator? Numerous new civil service departments would have to be established, including a Debt Management Office, to run its borrowing operations, a foreign service, complete with embassies in all major international capital cities and so on and so on. All of these would have to be conjured, in a tedious and expensive logistical phase that would come immediately after independence.
But though substantial, problems such as these are not big enough to knock out the whole pro-independence argument. Setting up structural governmental apparatus would be a draining exercise, and after the euphoria of winning independence, the tedium of the task would come as a sharp back-to-earth-with-a-bump corrective to the jubilant Holyrood mood. The language of hope and aspiration would very quickly turn to that of hard slog, of tasks that lie ahead and of jobs only half done.
