I'm not even sure what you're talking about now - I'm pointing out that neither side knows for sure whether we'd be better or worse off
My rum-addled eye could've still been sighting Roar, but I think he's read it anyway and replied.
But!
no we don't - you don't know how any trade talks would fare with the EU upon exiting the EU or what trade deals would be made with countries not in the EU... you're dealing with unknown events which can't realistically be estimated as they're dependent on all sorts of irrational and rational actions by numerous actors
Unknown or uncertain? You can hardly claim that we have no clue what the default negotiating positions of the EC and our most significant non-EU partners are. Estimating for the rest of the non-EU group wouldn't even be necessary; they are what, like ~11% of our imports/exports?
What's making things more complicated than they should be is our stance on free movement. Might as well flip a coin on that one for now, based on the polling, and forecast both for the globalist stance (known association options) and the populist stance (EFTA or the magic free-movement-free deal based on the EFTA).
Now, you may be dismissive of uncertainty analysis and non-linear models, but still: why can't the Leave campaign prepare at least a draft of their rational responses to rational options only? Isn't this what a part of any credible manifesto should be composed of? It wouldn't be hard.
They have the same access to information as the other guys. For most of their supporters, a document at the level of a business plan would do. Saying nothing on the issue is what creates the black chasm into which they are asking us to leap in the first place. There's no agreement on anything, unknown or uncertain, in their ranks.
Would you give them any money or trust? I wouldn't. They are arguing on the point of political ideals. And that's indeed something you can't quantify to feed into any sensible model I know of.
