It's a pretty sad state of affairs.

Why not make Scotland a 'State' of Great Britain? Likewise with England? (Sigh. And Wales). Or the United Kingdom, but that opens up a whole slew of wounds. Regardless, this retains a semblance of centralized government - and a Royal Family to lord over the Scots - but gives a distinct autonomy on the affairs which affect the citizens of the Great Nation of Scotland.

Essentially, complete and utter independence, particularly for a small populated country can be pretty hard on the people. And really this is the point: governments simply create problems for The People they represent. Which government will create the fewest problems?
