Unfortunately for Brexiteers who use this as an argument for No-Deal Brexit being an opportunity, however, geography was a big consideration for how pretty much every company in the world has set up its supply chains and partners.
"The geography is a bit of an issue for physical goods" when you're not producing goods cheap enough to cover the cost of transit. The UK does not produce cheap goods. Quite the opposite.
I don't think racing to the bottom in living standards to compete productively with China is something that people voting for Brexit had in mind.
The main issue people are concerned about is that the UK would be flooded with cheaper/sub standard goods (re. chlorinated chicken) that they can't differentiate between standard UK/EU products which are of a higher quality. Currently, US meat is outright banned in the EU, if there's an influx in cheap/chemically altered meats coming from the US which people can't differentiate from (this is partially due to the terms of the trading deal banning branding of goods as "Produced in the UK") then people are worried they'd accidentally end up buying them.
Not such a concern about where you’re going to get the £££ if all you’re buying is cheap junk in $$$ but even so there’s got to be cheaper places to buy cheap junk from and sure with the rules lifted why not just start producing cheap junk yourself!
