It is odd how the EU is becoming close to a religion - even thinking of leaving it is sinful and means people are xenophobic - even though the EU itself is extremely slow to engage with all outside countries.

The main reason that leaving the EU is such a Bad Idea is that the rest of the EU is unlikely to agree to a free trade deal. After all, if one could trade freely with EU countries, why would one put up with all the baggage...?
