Check any Scottish banknote and you'll see we still promise to pay the bearer in sterling.
Couple of points here.
Firstly IF Scotland were to vote for separation, the SNP would become completely redundant because they're only, to echo Billy Connolly's reference to the "wee pretendy parliament", a "wee pretendy political party" - inasmuch as they are in effect only really a single issue pressure group and simply don't give a toss about anything apart from separation and their referendum. Absolutely everything they do and think is governed hook, line and sinker by their sole objective of a yes vote. As a result in their book the best interests of the Scottish people in their every day lives are totally secondary to the SNP's sole raison d'etre.
Which brings me on to what would happen after a yes vote. There would now be no need for an SNP so politics would revert to a contest among the "real" parties whose priorities, whether you agree or disagree with them, revolve round proper mainstream politics and not the SNP's single issue.
So you are back where you started - so a yes vote would change absolutely nothing in that respect.
Secondly, I would also endorse yngwie's point that it doesn't seem all that long since the separatist lobby was singing the praises of Ireland and Iceland from the "arc of prosperity"
So... "you're not singing.. you're not singing... you're not singing any more" on that one because these countries have now become classic examples of small population bases finding it so easy to become financial basket cases when the going gets tough.
Instead you quote Norway (finite oil reserves are just for Christmas... separation is for life) Denmark and Sweden.
Right... so that'll be Norway where the standard rate of income tax is 28% (20% here), petrol is 25% dearer than it is here (see what having so much oil does for them!) and drink is so expensive that even if Salmond's EU challenged price hike were applied here, ours would still seem dirt cheap... etc etc....
Somebody also mentioned dictatorship. I really can't think of a more complete dictatorship than the SNP where all the party gofers and apparatchiks from Sturgeon downwards are all clones of Salmond (in mind if not in body )... right down to that silly patronising little giggle which he affects and which all the acolytes sycophantically copy.
I see your adopting the anti-brigades use of selective journalism Charles. You forgot to add that the average salary in Norway is almost £4000 a month. UK is just over £2000. The Norwegian government also uses its cash wisely and to the full benefit of its people hence Norway has the best standard of living in the world. Full years maternity / paternity leave paid. free kindergarten for children from 1 year old to allow parents to return to work if they so choose. Free healthcare for all. Free education and supported higher education. Free care for the elderly. Average lifespan of 78 for males and 83 for females. Norwegians on the whole are a lot better off than we are. And if they want a drink, which is not a cultural importance to them, they jump on a plane to Aberdeen airports duty free.
