Importing goods means we need them.
We aren’t forced to trade with the EU. We do so because we get a good deal doing so. We make that choice. By we, I mean businesses who are driven by profits - they’re making these choices.
Unless brexiteers think that the uk government/EU are making decisions about where to trade? We can trade with anyone we like (sanctions permitting), it just depends on what tariffs we pay/customs checks to go through etc - these will drive the commercial choices.
Remove ourselves from the EU = we (businesses) will then have to shop elsewhere and those prices will be higher because we chose to walk away from the best option.
We are a small country who offers very little relative to other countries.
That’s why the City of London and banking sector was the what Cameron then Theresa tried to protect. But quickly gave up as the year realised that the banks would just move. Back into the EU.
People want a UK which makes and grows it own; where we live off the fruits of our land etc.
That’s fine to have as a dream. Leaving the EU will not achieve it simply because we are in a capitalist global society.
