I say we take off and nuke the whole site from orbit. It's the only way
to be sure.
BTW those are called "mass drivers" and are great fun. I think Heinlein
gave a brief explication of why the moon was a great place to base space
exploration from, being mostly outside Earth's gravity well, having
plenty of power and materials and advantageous launch conditions. One
thing he sorta got wrong in the story was the limited supply of iron to
work as the vessel for the rocks, you can just use a carriage sort of
deal to bring the payload up to escape velocity, then capture and reuse
the carriage (and reclaim some energy in the process). Or go capture a
big nickel-iron asteroid and have plenty of magnetic stuff.

I'm reminded of when the lunar colony revolted in the novel The Moon
is a Harsh Mistress. They didn't have interplanetary weapons, but they
had big engineless freight ships, they had a magnetic catapult that
could hurl them beyond the moon's gravity, and they had lots of rock
to fill them with. They could simply aim them to land on earth instead
of going into harmless orbits.
They announced the time and the locations of the first wave of
rock-bombs.
Thousands of idiots showed up to watch the impacts. The TV news idiots
thought we'd been hit with nuclear weapons. Apparently they'd never
heard what happens when meteors hit the earth.
