This is going round in circles, because you know nothing about trade and you won't engage on specifics.
Oh I do engage on specifics Mistigri. I just hold a very different view to you.
You can trade with any country you like (except where embargoes apply) but where one country benefits from a trade agreement and the second doesn't, the latter will be at an economic and practical disadvantage
That is completely untrue. It depends on what each country has to sell.
You need to understand that it's not countries that trade with countries or even trading blocs trading with trading blocs.
It is individual customers, manufacturers and suppliers and they will force their Governments to comply - because if their Governments refuse to permit trade or make trade uncompetitive those Governments will not get the tax revenue and will have one huge unemployment bill to service.
So let-s hear no more about these stupid 'punishments (which are in themselves illegal) and start getting real.
We will trade successfully outside the EU.
We will look back at the REMAIN fear-mongering and wonder what all the fuss was about.
Y2K anybody?
