Correct, but the point you fail to appreciate is that the issues that emerge are a feature of Brexit, not a bug because of lack of planning or incompetence.
If you raise trade barriers and introduce friction where previously there was none you will have issues because management of these issues is now in the hands of Govt officials and management of an issue will never be as efficient as eliminating the issue.
The referendum could only be won by falsely pretending that we would have no issues if we left, indeed the claim was things would be better. As soon as we raised a trade barrier, built a lorry park or introduced an internal customs border, Brexit was lost.
Even worse, the UK then signed a deal where seeking mitigation of the effects of Brexit hands power to the EU, and this on top of leaving one sovereign UK nation still under the EU economic writ.
Our choice is stark, seek to diverge in an attempt to make Brexit ‘worth’ four years of division and pain and we will have more pain. Tack closely to EU rules and regulations to ease the pain and we become rule takers with no ability to shape the rules.
Reality is a woman.
