For me it's really simple. Scotland should be able to have a government that they have elected, so that the decisions made and laws passed will directly benefit the people of Scotland. Secondly, Scotland should be able to control it's own money, so that money made in Scotland stays in Scotland to better the country still.
We have 2 governments which we have elected- one in Holyrood and one in Westminster. I understand people's point that we didn't vote for the Tories (although, of course- we currently have a coalition which no one had the option to vote for!) but we have 5 million people against 63 million. Of course there were always be people who vote for a government and don't get their choice. I did not vote for the SNP, as you might be surprised to know
nor did I vote for the Tories. But I had a vote, as did every individual.
How will Scotland control its own money in an iScotland? You want a currency union. But even in a currency union, you are signing up to a fiscal contract, and the iScottish government wouldn't be able to tax and spend without the BoE's say so. With regards to policies, the same problem- 5 million versus 63- applies that we have with the current voting system. An iScotland would have a different economy and its government has to be able to control that economy, especially if it is based on the volatile oil market! Every single option involves Scotland ceding economic control to another body. It is a strange version of independence!
Because in the period between us voting yes, and actually becoming indy, the gvt of the rUk would be our gvt too. Still living off our taxes, but not representing us? Willing to negotiate against us? As they are willing to brief against us now, globally?
They would represent us in day to day matters, but in the context of iScotland's application to the EU, they would not represent us. That is a simple result of voting to leave the UK.
(I do understand they'd be in a difficult, and delicate position. Which is why the Edinburgh Agreement was that we'd all behave like decent human beings, seeking the best resolution for all... Shame that doesn't seem likely to happen.)
The Edinburgh Agreement said that the result of the referendum would be 'decisive and respected'. It also said 'The two governments are committed to continue to work together constructively in the light of the outcome, whatever it is, in the best interests of the people of Scotland and of the rest of the United Kingdom.' It does not say that 'we will give the people of Scotland everything that they want!'
The UK is only bound to negotiate for its own people. Not Scotland's. If, for example, Scotland doesn't take a share of its debt, then they do have the right to veto EU entrance.
