Your refusing to see this is about emotions not needs..
Why, yes, Mummmy because countries make trade deals based on needs and not emotions, emotions do not import food we need to live or maintain pipeline that supplies transport and you said we were not a 'dot of nothingness' so I posed the question, which no one has answered, that if that's so then name me one thing that we, the UK, has to supply or offer that any other country needs (and wants) that they (those other countries) cannot get elsewhere and likely for cheaper.
Because not a single country is coming forward, much less tripping over themselves, to offer us a trade deal that has more favourable terms than we have under the EU. Not one!
Emotions keep the power on when you want to cook or pipe gas around so you don't freeze to death in Winter.
It's downright frightening that some actually believe they have nothing because I've sadly had the unfortunate experience of actually living in places where people truly have FA, the infrastructure is so poor and fragile, and they are really, really not nice places to live.
