Not really. Unlike the Brexit the Scottish actually have the perspective to become a part of the single market after they achieved independence. It's a clear plan. Unlike "We're gonna rebuild the commonwealth and create the Empire 2.0 and everybody will give us FTAs because they love us.".
As Scotland was already a part of a member of the EU, it should fulfill the requirements to join.
*this isn't a positive thing.. that would mean requesting re admittance.. which would be harder as the vote required by other EU members would have to be unanimously in favour.
As part of the UK, when article 50 is triggered, a newly independent Scotland would just as likely need to request re-admittance to the EU, as it would 1st time admittance.. either is still a lengthy process. And until such time as Scotland is independent of the UK, it is in no position to negotiate or discuss joining the EU as an independent country. Even if they could discuss the possibility with EU members, there are still no guarantees that once an official request was submitted, that it would be accepted.. and sorry, i'm just not willing to accept a back-room handshake and the word of a bureaucrat on such an important matter.
there is far more uncertainty for a Scotland that finds itself independent from the UK, hoping for admittance into a struggling EU, than there is in remaining a part of the UK, as it weathers the storm of a Brexit.
also let me add another point..
i don't know anyone who honestly thinks that everything is going to be great, or that we wont have a proper tough time moving forward, regardless.
in fact, anyone who thinks that is what most people are thinking, are probably far more naive than the few who maybe do think everything will be rainbows and unicorns.
any salesman will tell you, you have a far greater chance of getting a sale if you know you will, than if you know you wont. sometimes life deals a hand where the only chance for success, is based on simple optimism! with anything other, resulting in failure.
