Indeed, and I believe mankind would be far more enlightened if we did away with something as silly as the nation state, especially when we so readily discriminate based upon one's nationality. It's absurd. The very idea of equality is for people to be treated fairly regardless of where you're from, your race, gender, religion and so on. The freedom of movement we enjoy under the EU doesn't go far enough towards that goal, but as you rightly say, it's a darn sight further towards it than anywhere else on the planet, which is why it shames me that we're throwing it away so breezily. It's arguably the greatest political achievement of the last century.
