So we won't have any Trade Agreementsif we leave. So what. Remember they work both ways.
We have No Trade Deals with the USA, but Apple, Microsoft don't do so bad. We will have no trade deal with the failing EU if we leave and do you really think that VW, BMW Renault and Citroen are going to cut off their noses to spite their face by not selling or putting up the prices of their products.
All a Trade Deal is is an agreement between the parties regarding Duty Levels, taxation and manufacturing standards etc.
No one knows exactly what will happen if we leave or if we stay but on the balance of probability the EU will fail in the not too distant future whether we stay or not and I for one do not wish this country to be dragged through the mill because of a failing Organization run by an unelected and unaccountable group of hasbeens
Some people have quoted the " younger generation ". I am just very glad this generation, the vast majority of which are very risk adverse, was not around in 1939, because if they were then I don't think we would be now.
My personal opinion.
