Nope sorry may have crossed wires, what I mean is that the UK if votes for Brexit, the people are not voting to leave the EEA. If the EU / EEA members require the UK to leave because of the Brexit then so be it.
If negotiations don't get special exemptions to free movement of workers, then yes we would be leaving be default. I just don't think a brexit vote means automatically the negotiations team doesn't try to get exemptions to stay.
There are benefits of course to leaving the EEA, stop passporting and make companies pay UK taxes more easily. Enforce UK regulations , whilst I don't agree with some UK regulations on financial products. The very fact that I can move my business to another EEA country and trade back to the UK over the internet and totally avoid FCA rules is odd.
