If you think the value of gold has remained stable, that's only because you're only measuring it during times and places of stability. See how much bread your ounce of gold buys you when there's no bread to buy. In a real crisis, the value of gold drops to near zero, just like fiat money does. No hungry person cares about electronic coating.

The best you can say is that gold is tangible, portable and universal. So you can bring it with you (often in the form of jewelry) as you flee, and it will likely return to value in some other time/place.
