"The last remnant of physical objectivity of space-time" is disclosed in the
case of a continuous family of spatially non-compact models of general
relativity (GR). The {\it physical individuation} of point-events is furnished
by the intrinsic degrees of freedom of the gravitational field, (viz, the {\it
Dirac observables}) that represent - as it were - the {\it ontic} part of the
metric field. The physical role of the {\it epistemic} part (viz. the {\it
gauge} variables) is likewise clarified as emboding the unavoidable
non-inertial aspects of GR. At the end the philosophical import of the {\it
Hole Argument} is substantially weakened and in fact the Argument itself
dis-solved, while a specific four-dimensional {\it holistic and structuralist}
view of space-time, (called {\it point-structuralism}), emerges, including
elements common to the tradition of both {\it substantivalism} and {\it
relationism}. The observables of our models undergo real {\it temporal change}:
this gives new evidence to the fact that statements like the {\it frozen-time}
character of evolution, as other ontological claims about GR, are {\it model
dependent}. \medskip Forthcoming in Studies in History and Philosophy of Modern
