Thanks Statistically and Santana
Some other questions:
"The Yes campaign likes to tell us all that Scotland's economy is very different and that its priorities re spending are different. Under this line of argument, it doesn't make sense to use a currency which would be engineered for the benefit of a country with different needs to yours." I can see that this would be less than ideal for iScotland, but I'm not sure why this would be a huge negative for rUK.
" it's undeniable that the Scottish economy is considerably smaller than that of rUK..we would never be able to bail rUK out, but they could bail us out if it was needed". Granted. But what is the actual likelihood of this having to happen in the foreseeable future? In a CU, it seems like a theoretical risk.
"iScotland would be wanting to take a different approach on numerous elements of tax and spending which could easily cause our economies to diverge" Again, granted. But to what degree? And given that the Scottish economy is considerably smaller, what serious impact could that divergence really have?
"A drop in UK credit rating could happen for example - and that's a massive risk and could easily hurt more than the transaction costs or job losses from not having the union". This would depend on the risks created by a different tax and spending policies in an iScotland? And would need to balanced against the potential impact of transaction costs, job losses and the initial shock of splitting the Scottish economy from Sterling?
Sorry, for so many questions, just interested in the genuine barriers to a CU, apart from public mood.
RE Trident - I am absolutely for getting rid of Trident, but I would prefer to see it decommissioned than simply moved elsewhere. If decommissioning was on the table then I'd take that above all else. If rUK wished to host Trident then that's really up to rUK. Obviously it would take time to place Trident elsewhere and if there was a necessary overlap between rUK preparing to host Trident and a useful period of CU, then I wouldn't see that as a barrier to such an arrangement. But I would prefer it if it was taken as an opportunity for rUK to reject Trident too.
