An Oxford logician, Jeffrey Ketland, has laid out perfectly in this essay, "Elite technocracy vs Liberal democracy" my reasons for voting Leave. His arguments, though less well expressed in my head or on GN threads, are what I've been thinking.
Below is part of his conclusion. He, btw, inclined more towards Remain although he says he didn't vote in the end. I love his detachment and logical analysis.
"The Leave side, represents the anti-authoritarian tradition of liberal democracy, while the Remain side represents the authoritarian illiberal tradition of elite technocracy. What occurred on 23 June 2016 was a kind of revolt, with significant support from ordinary working-class voters, against an undemocratic supranational authority, to which they did not consent. Perhaps the European project will flounder, and even begin to unravel, because its underlying political philosophy was never that of democracy or liberalism, but rather that of an elite managerial technocracy. Or perhaps the shock of the Brexit vote and subsequent negotiations will lead to democratic reforms.
As mentioned above, it may be correct that, in economic terms, a decision to leave the EU would be unwise, and it may well encourage nationalist sentiments. However, that decision was an expression of an anti-authoritarian, democratic and indeed liberal outlook. In the long term, I believe that the most significant outcome is a weakening of a non-accountable, technocratic superstate, and a strengthening of liberal democracy."
