The degree of EU involvement has messed up all kinds of things.  I remember milk being 20p+ a pint about 30 years ago.  Now it's £1 for 4 pints - the same price, despite lots of inflation.  Dairy farmers are selling the stuff for less than the cost of the feed for the cows - not because they're charitable but because this qualifies them for a massive subsidy from the EU.

Our choices will be to either:

• Give the farmers subsidies and continue the EU-style expensive state-controlled madness, taxing the poor population to hand it to rich land-owners
• Accept the cheap milk from the EU and let our farmers all go out of business
• Allow farmers/supermarkets to charge the actual market price (perhaps £2 for a 4-pint bottle) and protect UK farmers from artificially cheap subsidised milk from the EU by slapping a big amount of import duty on it - which would enrage the EU and probably start a trade war, where they'd slap a big tax on something we export.  This could also lead to complaints about food poverty too, as people would need to pay the actual price for the first time, not a false taxpayer-subsidised one

Just one example of the sort of knots we will need to untie as we get out of it all.  I reckon it's going to be very difficult to trade with the EU if we don't just comply with their every wish and continue as before.
