How is 43 km of moon armor a thin surface by any means?

Consider that the earth is ~12700 km in diameter

Yeah, but from surface to space it's ruthly 100 km, so 43 km is quite the cover. Then again, I get what you are saying. I gues it's a matter of perspective.

Ah I see. Although the comic spreads the moon "relatively", it presents it absolutely. Although interesting in by itself it does feels it's missing something.
