I'm still not sure whether the EU would let Scotland in straight away (or let it stay as a current member while England leaves which is another possibility) but even if it doesn't, Scotland could join EFTA (it's a better fit than the full UK to the current members) and remain in the free trade area as it accepts the principle of the four freedoms (unlike the Brexiteers).
In terms of whether it would survive economically, if a country with the resources that Scotland has (tourism, water, food, software, call centres, forestry, whisky and gin, fishing, renewables, biotech, financial services) can't survive independently, then doesn't that say more about what the Union has done for us?
Note, I didn't include oil and gas in that list: it is the bonus, not the raison d'être of the economic case. Yes, it's galling that oil was discovered in Scottish waters and Scotland ended up poorer
. Look at the decline in the Scottish population in the 70s
. It's frustrating that no Sovereign Wealth Fund was set up (unlike Norway) which could help both prepare for the future, when the oil runs out and help smooth out the challenges faced by the industry caused by fluctuations in the price of oil (which ironically, at the moment will be worth more as it's priced in dollars). But that's history.
Yes, Scotland had a deficit last year. You don't judge a country on a single year. Otherwise the UK would have been judged incapable of independence following the financial crisis in 2008.
What is the average deficit over the last 5 years? 10 years? How much of that deficit is servicing the "UK" debt? If Scotland has to continue paying that interest, what share of the assets will she also be due? The Bank of England, despite its name, also "belongs" to Scotland.
The deficit also assumes the same spending decisions as Westminster - including things like Trident which an independent Scotland might not choose to pay for.
Why can Denmark and Finland (similar sizes) survive on their own?
I'm not saying that the initial adjustment period wouldn't be tough - especially if England is difficult about the process, but I would argue that it may be less tough than the adjustment period that FUKD is going to have to go through if it exits both the EU and Single Market.
I fully understand why people would say that they prefer to be part of the UK and that they're proud to be British (OK, at the moment I'm having difficult with that one - but I respect people's right to be proud of it even if at the moment I despair about where the UK is going) as well as, or instead of, Scottish.
I don't accept the "too wee, too poor" argument.
