We had a long discussion in my high school physics class about this. There are many more answers, including using the barometer as a measuring stick to measure the length of the building’s shadow on the ground, and applying trig to get the height; also going to the building engineer and trading the barometer for a copy of the building blueprints.
The carrying capacity of Earth for saints would be larger than for real people.
Real people do not distribute things equitably, and that lowers the carrying capacity.

I like the “Art of War”, but I can’t remember what chapter this quote was at.

“As far as gear goes, you don’t need any of that ■■■■. Nobody needs that stuff. If it makes people feel better to have a garage full of the very best gear available, great, I’ll sell it to them.”

I get the Joe meme, but that’s actually a pretty long-running joke. Attributed either to a German officer in WWII or a Soviet officer just after WWII, the complaint was that it’s hard to plan against American military doctrine because the American military never follows their own doctrine.

“There are two novels that can change a bookish fourteen-year old’s life: The Lord of the Rings and Atlas Shrugged.

The other, of course, involves orcs.”
