But in today's international world currency never operates on a vacuum. It is very naive to suggest that eg as Britain is not in the Euro it is not affected by the Euro.
I don't think that has been suggested.
Reasons currency union would be good for rUK:
Scotland would take on a share of the debt
Scotland should take it on anyway.
All of England's exports to Scotland would continue unimpeded (ie without additional cost)
All of England's imports from Scotland would do the same ( imports eg electricity, oil etc)
If Scotland wants to price itself out of its export markets, then I don't see why anyone would object.
The currency would continue to have oil backing it
Mmm, that helps.
Doesn't really matter though, currency union isn't a deal breaker for anyone.
It ought to be. Currency union destroyed Spain, Portugal, Greece and Italy because they were in the wrong one. It speaks volumes to me at the lack of critical thinking on this issue that you wave it away as an irrelevance.
