That doesn't mean, however, that a supranational entity such as the EU necessarily is the right solution to each and every problem in the future. Sure, perhaps a federal superstate isn't the answer - I certainly don't think it's a great answer for local gov, taxes or accountability, though given the world we live in surrounded by hostile autocracies I think having armed forces and trade at that level is advantageous, so that's why I'm for it, but further devolution of powers would be ideal in my view, if coupled with free movement of people and goods at a federal level. Given that I see no reason for Nations to exist. Free movement of people at least within large federal states and later globally is a worthy ideal to strive towards - why should the place of your birth dictate the rights and opportunities accorded to you? Why should nation states claim the right to bestow and strip citizenship?
