Actually, @mcfc1632 is absolutely spot on with his point on Scottish independence, Brexit killed it.Your argument has echoes of the Remain argument in the EU referendum, vote to stay in a union you no longer support because a vote to leave will hurt you financially. Scots definitely care about the economy, but this vote when it comes will be an emotional one imo. I can certainly see the logic of the Scots going their own way rather than being a reluctant, resentful partner in a union they no longer support for purely financial reasons. This would probably be a good thing because if they keep electing the likes of Sturgeon and Blackford, whilst we’re electing the likes of Boris and Gove, we’re going to end up hating each other.
Them becoming independent of London was pretty straight forward but now it’s almost impossible without totally destroying themselves.
The main two problems are :
1) They’ll have to spend a significant time out of the UK and EU. The EU won’t even start their approval process to become a member until they’re on their own, this means several years of being outside both, which, to say it would be catastrophic, is an understatement. There’s also the chance the EU won’t let them in, due to debt and GDP or their relationship with the UK.
2) The border, there will need to be infrastructure on the border, this will be irreversible if they leave, due to MFN. We’ve managed to negotiate NI being in both unions for trade but we can’t for Scotland, due to point 1. above.
Even if a UK Prime Minister grants another vote, they won’t, they’ll continue to kick it down the can indefinitely, as none want to be remembered as the PM who lost the union, when the evidence presents itself they’ll vote no anyway.
