Have you considered how farming works in the EU? Do you understand the money that comes back to farmers in subsidies to ensure we all have food? (right or wrong I'm not debating subsidies here but take them away and there is no incentive to farm especially when all other EU farmers are being subsidised, then where do we get our home grown food from?)
It's all well and good going for a "Hard Brexit" but at least understand some of the issues that need to be resolved before anyone can think of doing that. I'll be stocking up on some stuff before it happens, better to be safe than sorry.
