I do think some of those things sound like benefits.
Now, some of those benefits are only made possible because the UK has less sovereignty and less say in what goes on in the EU (e.g. the tax havens, which it seems we were blocking). I'm not sure that's what the Leave campaign was arguing for, but honestly, as far as the world goes, I agree that's an upside.
Some of the benefits are risible. Pint glasses are a particularly silly example, but the wine one is very bad too. I suppose some people would rather import Australian wine more cheaply, but for my money I'd much rather have cheap French, Spanish, Italian, and even German and Austrian wines. (I suppose that's me being snobby and the fans of a very full bodied Cab Sav might be delighted.)
The factory one has to be balanced, I suppose, against all the factories have closed, but for the people of Wigan I'm sure it's an upside.
But even if some of these things are benefits, and I agree that some are, I'm afraid that I still think they are vastly outweighed by the drawbacks.
However, thank you for providing examples! And really they ought not all to be scoffed at--this is what people were asking for.
