It's not a line of inquiry I would majorly press, since the whole thing is a 'done deal' now. However I do wonder what made you come down on that particular side, since it should have been clear that a gang of Thatcherite neoliberal-monetarists weren't leaving a neoliberal-monetarist economic union to become something else. Or that it would magically increase the UK's geopolitical influence among large power blocs. That in particular baffled me.
Aside from the ludicrously rose-tinted view of the EU from many centrist-type remainers, I think the charge that a huge number of Brexiters were and are simply clueless regarding the central facts of the problem is a justified charge. Almost every single point of contention the average Brexit voter puts forward as a reason is pure fantasy or a talking point from The Sun. Don't get me wrong, I think it would be crazy to say 'no-one can ever leave the EU, you're in or nothing', but the actual reasons given for departing were 99% fiction.
