The following context is about graffiti and graffiti artists. Does the highlighted sentence mean "Artist's sheer physical elusiveness (the absence of their identity) is perhaps both a radical force and a threat for their practices"?
Context:
They are out there but you never see them carry out their work, so you neither know who they are nor, often, how they managed to access the site in question. As such, the pieces effectively perform their exponents’ disappearance. And that is perhaps the radical force or threat of their practice: their sheer physical elusiveness.
