Few things:
I don't understand why so many of you are all warm and cuddly for the EU? Its fundamentally un-democratic and is completely dysfunctional.
Scotland would probably be forced to adopt the Euro. Really guys, you want to do that? Really. Well what ever floats your boat. The Euro is fundamentally FUBAR'd, keeping it going is going to be a major headache for years, its not even clear that the Euro can ultimately be saved.
Mortgages are in Pounds Sterling, lenders have no obligation to switch over to Euros. Could be fun.
Scotland has no power to call a referendum. They can call a fake one, but its fake, so would simply put pressure on UK to allow self determination. Given that leaving EU is going to be a stupendous amount of work, I can't see UK Gov being too keen on IndyRef2 any time soon.
SNP has no mandate for IndyRef2. Yep they could ask the Greens to help them get legislation through Scottish parliament, but that's not quite the same thing. I'm not saying UK Gov would stand in the way of self-determination, but it wouldn't rush to help you get that legislation through Westminster: bigger fish to fry and all that.
An independent Scotland would be immediately insolvent as it currently operates. North Sea oil is never coming back as it was--fracking has seen to that--so there will no longer be that Resources cushion. Sure, Scotland could still be independent and a great nation, it would just require a substantial tightening of the belt, you all up for that? Have a real hard think about what that would actually mean.
At this moment in time Nicola Sturgeon is throwing her toys out of the pram. If you all feel the same in 6 or 7 years time then your chance will come again. However by then you will all have chilled out a bit, and I'm guessing the economic realities will then prevail. And as for joining the EU, I reckon that institution will look even less attractive by then.
