You have missed the point Leo

Brexit will:
1. Give us our sovereignty back ! Like the man on the sinking ship retains a certain 'dignity' while doing it. We could have a certain interim period of 'self determination' until jumping into some kind of mini TTIP with uncle Donald over the pond. (Then you can forget sovereignty for evermore).
2. We could also leave the Eurovision song contest

3. A future People's Republic of England could bring everything under public ownership without having to worry about EU. rules (unlikely scenario).
4. On a more serious note both the major parties are seriously crippled (this will be slightly more delayed for the Tories) and if the next election is held mainly on the management of Brexit then we could see the breakdown of the 2 party system in the UK.
5. We could now see a united Ireland in our lifetime.
