Re: Stupid?
The real benefit is regaining most of sovereignty a past __treasonous__ government tricked people out of via the 1975 Referendum (I could not vote in!!!) leading to the Common Market Act, by not telling them that __they knew__ it was really a political/legal/finance EU "Wolf" in Common Market "sheeps" clothing i.e. a Collectivist Trojan Horse.
By exiting the EU, we will be able to scrap a mountain of bureaucratic, anti-capitalist, crony-capitalist regulations/'laws' which hamper SME business, regain control over our borders, regain full control over taxation, stop wasting Billions on anti-capitalist/wasteful agricultural subsidies and other counter productive & political vanity projects, including the powerless EU 'parliament' and it's pointless regular migrations, and not be part of an effectively tyrannical criminal organisation with no valid accounting for many years which is getting very close to the edge of a very steep financial cliff face.
A lot of the freed up EU 'fees' (extortion) could be redirected to more productive investments like much delayed infrastructure repairs/replacement and other things net helping the UK get better, maybe even allow less taxation, so more available for genuinely productive private use.
Trade will happen if two parties chose to, it doesn't have to require inter-nation agreements, if inter-nation agreements are needed, this won't require the EU at all and probably will be much faster, easier and cheaper!
When a major Euro-zone member country fails (e.g. Italy is a current favourite) the Euro is probably toast, it is doubtful that the EU will survive for long after that! When the UK has exited the EU, we will probably see far less fallout from such a collapse.
