   Basically, moon bases need to be underground to prevent micrometeoroids from messing them up, and any bigger impact like this is going to wipe out anything we build, even underground.

   All the more reason Earth is pretty awesome!

   Fun fact: moon regolith is made of ~45% oxygen, so in a roundabout way digging underground is kind of like having an atmosphere.

      I like your reasoning about oxygen and would like to contribute the factoid that the molecular weight of CO₂ is over 72% oxygen. We really need to be spewing more of this stuff into the atmosphere to improve its oxygenation. Obviously O₂ would be best, but CO₂ is much more practical, and still gets us 72%.
