As much as I am enjoying our little conversation here, there comes a point where someone needs to admit that they are in a little bit over their head and arguing for argument's sake. I'm afraid that you have just reached that point. Your original point of contention was that Scotland's financial services industry is insigificant, which is simply not true. Your most recent post here makes it clear that you are unaware of the fact that (1) RBS owns Natwest, and (2) the British Government (of which Scotland is still currently a part) made similiar investments in both RBS and Lloyds TSB as part of the 2008 UK rescue package.
I know that the British Government intervened in several banks during the financial crisis. That is not the point I am trying to make. If a large proportion of RBS, Scotland's largest bank, is owned by the British Government, that means that a large amount of RBS is owned by the BRITISH people. And England and Wales make up 90% of Britain's population. That makes it OUR bank, not Scotlands.
