I really enjoyed this article, a couple of months ago, when I first read it Hive account@goldmoney-inc! I love economics and the history of how money is selected in each culture.
This essay describes an element that I hadn't considered.

A young man thinks he has no need to save, because his back is strong and his necessary commodities for life are easy to obtain.
He will find when he gets old, that he has outlived his supply of saved food, lumber, etc. Even though he stored away extra, they didn't last.
Gold is a way to preserve that value, for eternity. To buy what you need later, without loss over time.
