Just work within the very reliable regulations of the World Trade Organisation and sod the EU.

We can trade merrily along, exempt VAT and duty in or out with the 27 EU member states and crack on!

One thing we need to do is assure all citizens of EU heritage who decided to settle here and build a life pre-Brexit that they are guaranteed the right to remain here with all of the same rights as a British citizen. Of course it will be incumbent on the EU to reciprocate with the same deal for British citizens settled in any one of the 27 EU member states.

Not hard is it? Like you say Alto, someone needs to grow a pair and just do it!
