Borderless society is not an option under current draconian nation state law, but (as suggested by @cryptofunk) it's upto us to continue to develop and advocate using the distributed blockchain paradigm in order to devalue the current socio-political border state, and by any other means, towards the liberation for all earthlings across our beautiful planet.
Brexit/Remain are a two sided arguement over an old coin.

Though the "economic union" is not in the economic interests of any particular populace, vs a centralised cabal of bankers, it has been a fairly open bordered arrangement for the free movement of people within that expanded "union" - I therefore lament the multicultural communities that have grown in cosmopolitan regions and are being assfucked right now.

For better or for worse, this is what I think of the whole Brexit affair
