Okay, I'm at my desk so I can type out a better response.

Gold is immutable, it cannot be tainted or destroyed. It can be lost and recovered through mining/extraction difficulty. This comes at a cost, that cost to yield is roughly 1 to 2% annually.

Gold is the best conductive metal out there. it's used in critical components like connectors and switches for it's high rate of conductivity. Gold is also malleable, a small piece can be hammered out into a relatively large sheet, hell whisper thin you could put it on food. Bitcoin mining requires gold for efficiency.

it is by far the best, most useful metal out there and it's also shiny. Come rain, sandstorm, earthquake, nuclear winter - gold will still be gold, still be recoverable at a PoW cost and will still have a market.

This is why it became money - not because it has scarcity or looks good, but because of all of these properties discovered over millennia.

I don't argue with the Pharaohs.
