However, you can still define a “gravitational stress-energy pseudotensor”, which although meaningless at a single point nonetheless gives sensible results when integrated, yielding the total energy and momentum in a region surrounded by flat spacetime, and the fluxes of energy and momentum in or out of such a region.

In GR, you can’t do that, but you can, for example, integrate this pseudotensor over several wavelengths of a gravitational wave to get a meaningful result for the energy and momentum that it’s carrying — a result that will tell you how much energy the wave will deposit in various kinds of gravity wave detectors.
