Gold, silver, etc., were more attractive in ancient times due to their portability. Today that's not such an advantage. Portland cement, for example, is in high demand worldwide at all times YET not everyone is equipped to manufacture it ~ not that the primary component is in short supply, but typically coal fired kilns are used.
Got Coal? Got Portland!
It keeps well ~ and is portable with modern transport equipment.

It requires massive amounts of fuel to make, and a fair amount to transport. Hm.
Does it keep well? I know a bag of concret will set in my garage after a month or two, lol. Maybe that’s after lime is mixed in?

“Portable”? Cement??
A Saturn 5 is “portable” too - with the right equipment. No, “portable” means what one can carry, naked, running from hordes of screaming zombies.
