In an increasingly integrated, globalised world, such isolationism curtails the freedom a nation needs to exercise the economic and trade decisions and activities needed for long-term economic prosperity and political success.
Regardless of the outcome of tomorrow's Referendum, Scotland will not stay the same. With 97% of the electorate registered to vote, tensions between the 'Yes' campaign and 'Better Together' are tangible.
At times, justified fear has a legitimate place in politics. Fear of uncertainty, fear of investor confidence - these are things that the Scottish economy will consider constantly as an independent country - to ignore them now is to prefer utopia to reality.
I voted No but I suspect I did so for entirely distinct reasons than many of my fellow No-voters would wish, and many Yes-voters would imagine. These reasons are purely personal: I believe the following policy areas are the most crucial in improving UK society as a whole...
Scotland is a country that I adore, but she is letting herself down. Scotland is having a tantrum and behaving like a petulant teenager. And like a petulant teenager, she is neither big nor strong enough to go it alone. Get over yourself Scotland. You are a small country, deal with it... What's so special about Scotland anyway? Well, a lot actually. I think it's one of the greatest nations in human history. For a small country, it has and continues to contribute a disproportionately large amount to the world. Scotland's offerings in science, medicine, technology, music, engineering, entertainment and art are unparalleled. That's not to mention the landscape, the cities, the drinks and the epic women. But that doesn't mean you have to break off and go it alone
People are waking up, and the BBC and the Labour Party can't stop them. History is within Scotland's grasp, a beautiful and inspiring climax; self-determination is possible. If it's a YES, we can see a great renaissance and a new age in Scotland. Maybe the next Alan McGee of the 21st Century won't have to go to London to make his mark in the world, and I believe in that.
We have been talking about localism for years. 'The time has come to disperse power in Britain more widely', said Cameron and Clegg in the 2010 coalition agreement. From Whitechapel to West Lothian, it's time they acted upon that sentiment.
The undeniable cynicism of justifying fear will leave itself open to detraction. But realism is better than wish thinking. So if you're voting No because you're scared of the risks, be reassured. It's a perfectly reasonable response to the wild unpredictability of separation.
The Scottish independence referendum (#IndyRef) is both encouraging and terrifying at the same time. To see voter registration at 97% of the adult population is encouraging. People have never been so active, engaged and motivated in politics in living memory. Turnout in the 1979 referendum was only 33%, too low for the outcome to count.
Unless you've been living inside a black hole since the early 1990s, the allusions to the current referendum must be apparent. For as a child of Britain, unable to affect the potential break up of the United Kingdom on Thursday, the naïve response is to feel this is unfair...
Whichever way it goes, I will be challenging myself to remain steady in an idea of global Britishness. I won't be accepting the Scottish nationalists' invitation to think of myself as reduced and obliged to come to terms with my Englishness, but will be working to enhance strong, ongoing narratives about a Britain that embraces and integrates.
There is also an obvious 'other' choice on the table come next May, equally able to polarise opinion, and also concerning who holds power and influence. In eight months time we may be crediting a certain Mr Farage with emulating Mr Salmond and igniting interest in politics across the whole of the UK, though I'm certain not all will thank him for it.
A few years ago, my mum moved from Lanark to the Borders. That's where I go now when I go home. On my most recent visit, we walked for hours through the Border hills. The landscape was beautiful, with the heather in its purple splendour and the odd thistle bobbing in the wind. But you know the best thing of all about that part of the country? There is no border.
The Scottish Independence Referendum is drawing to a close. Many questions remain unanswered, but there is one question that sticks out. What currency would an independent Scotland use?
The only label that should matter for the future of Scotland is 'Scottish' (or resident of Scotland if we want to be accurate about these sorts of things). Let's hope people remember that when they hit the ballot box.
Whatever you think about Alex Salmond - be it proprietor of independence or destroyer of the glorious union - he is right about one thing: the Scottish Independence referendum is a 'once in a generation' opportunity. It is the battle of disparity, the war of disillusionment, the fist-fight of hope vs. cold hard political reality.
