Are you from UK? Here in France there are people who want to quit too. I am to stay, EU was made for economic benefits and avoid another conflict like WWI, WWII and others like Napoleonian Wars etc. European Union has deficiencies of course, but destroying it would be a so big collapse...
The collapse of the EU would be like as if the US made each state it's own country. It would be a shit storm for travel, business and economics in the region.
