Many of us in the UK only wanted Brexit so we could keep control over our population: we are a small island with limited space and resources. Like many, I actually voted to remain in the EU, even though it was/is far from perfect.
No, personally, I think the hard EU line is because they are peeved we are leaving and will no longer contribute money to the project. EU nations need our trade. We will be free to trade with the world on our terms.
EU - get real!
