OK, I'll bite...here's just one reason...freedom of movement. I worked in the EU half of my working life. It was great, financially and culturally.
Fair enough if you made use of it then it would be valuable to you as it was to me when I did it. You do know that puts us in a very small minority of the country though right? Probably around 2-5% at the very most will ever live and work abroad and much of that won't be in the EU. You can't really complain that people gave up a 'benefit' they weren't using for one they will (free trade agreements with the ROTW).
It's not like we can't go work abroad, there'll just be some more paperwork this time, same as when I lived and worked in the USA. The additional complexity of moving abroad for work outside the EU is not substantial compared to the complexity of doing so in the EU regardless of previous rights - you still have mountains of official and unofficial paperwork to wade through and much to organise. Its a marginal inconvenience to be completed before you depart and then its no different unless you commit a crime and get deported.
