Still hard to comprehend. We have quite a bit on hand too. Not gold on paper but tangible gold. Have for years. Would make some nice bricks. I am one of millions that has some.
Gold can be hammered into foils that are quite thin, and ancient monuments which were formerly allegedly covered with gold have A) been stripped, generally by other ancient groups, and B) probably didn’t cover the entire interiors of palaces and temples (paint was the rest; “if the lion’s skin won’t reach, you must patch it out with the fox’.”). :’)
