The Cone of Light would function between galactic clusters, but not within the local galactic cluster. Within the local galactic cluster there would be no way to travel intergalactically since no power source, including nuclear, would last the several million years needed to make the trip. We might populate the Milky Way were it not for Congress, but we wouldn't ever go beyond the Milky Way.

(Assuming the density of dark energy is high enough in between galaxies.)
Go to the Milky Way? The Three Musketeers can't even afford to go to Mars.
