The only reason gold is valuable is because humanity as a whole has agreed that it's valuable.
Somebody already said it, it's just a rock.
If you can't eat or drink it, wear it, keep yourself warm with it, defend yourself with it or wipe your ass with it, it really doesn't have any intrinsic value.
I used to have a supervisor who was constantly preaching that you should store gold. Get as much gold as you could, hide it and keep it for "The Collapse".
Every time he said it I asked hiwh"What are you going to do when the economy crashes and the first thing the government does is Outlaws all gold transactions?" He never had an answer for that.
