"Bama Brian; If you've got control of the high ground, you don't need
laser cannon. Rocks will do quite well, and solar mirrors can become a
serious threat."

I've mentioned a few hundred times about using moon rocks as deployed
away from the LSE-CM/ISS, as from that nifty vantage point it would be
extremely efficient to pulverise just about anywhere upon the moon with
sufficient impact velocity as to vaporise as much as a million fold
more of the moon per tonne of whatever moon-rock is utilized.

And, I totally agree that large solar farms of mylar mirrors would
really be impressive, at not only processing lunar basalt but for
frying as many butts on Earth as you'd like.

However, due to the nasty secondary hard-x-rays or photon recoil
aspects of being fully raw solar illuminated, the lunar surface
environment will remain somewhat off-limits, as even if you've got a
good stash of banked bone-marrow back home, it will not do you much
good if you're stuck on the moon without a good sized and thick walled
geode pocket to reside within.

However, residing within the CM/ISS that's tethered at perhaps 64,000
km above the lunar deck, your being surrounded by 50t/m2 worth of lunar
basalt placed into the massive sphere that's surrounding yourself, as
lo and behold you should be capable of holding onto your DNA/RNA for up
a year at a time without need of that banked bone marrow.
