Venetian Graffiti n.2

My photo of another interesting graffiti on a Venice street wall
La patria sarà quando tutti saremo stranieri
literally:
There’ll be a homeland only when we’re all foreigners.

A paradox that overturns the traditional idea of homeland: not an identity that excludes, but a condition that includes.
Only when no one is “at home” can we all feel at home.
Is it utopia, or simply a definition still ahead of its time?
