The right to the city is an empty siginifier

This poses a problem: to claim the right to the city is, in effect, to claim a right to something that no longer exists (if it ever truly did). Furthermore, the right to the city is an empty signifier. Everything depends on who gets to fill it with meaning. The financiers and developers can claim it, and have every right to do so. But then so can the homeless and the sans-papiers. We inevitably have to confront the question of whose rights are being identified, while recognizing, as Marx puts it in Capital, that "between equal rights force decides." The definition of the right is itself an object of struggle, and that struggle has to proceed concomitantly with the struggle to materialize it.
