We are now in the ludicrous position of asserting that we must accept huge amounts of precisely such EU law, without changing an iota, because it is essential for our economic health — and when we no longer have any ability to influence these laws as they are made.
In that respect we are truly headed for the status of colony — and many will struggle to see the economic or political advantages of that particular arrangement.
It is also clear that by surrendering control over our rulebook for goods and agrifoods (and much else besides) we will make it much more difficult to do free trade deals. And then there is the further impediment of having to argue for an impractical and undeliverable customs arrangement unlike any other in existence.
What is even more disturbing is that this is our opening bid. This is already how we see the end state for the UK — before the other side has made its counter-offer.
