If you look at my previous post, I said gold won't retain value in extreme circumstances, not sure how you got that I was saying it would have value in extreme circumstances. Value is nothing more than a measure of what people will pay for something. I absolutely agree that in extreme situations, the only things with value would be food, water and I would argue weapons to prevent others from taking your food and water. I merely said, if you are worried about retaining value and wanted a medium of exchange that is exchangeable even today, gold is probably the best way to go. The government doesn't recognize gold as legal tender, but I imagine if you tried to buy anything with gold, you would have better luck than cryptocurrency. Also in the crash of 2008, look at the price of gold. It went through the roof. Why? Because people wanted a store of value that was secure despite financial turbulence. Not sure why you are referencing ancient Egypt as iron had more value than gold and I am not saying the governments need to go to the gold standard, I am just saying if you want a stable source of value, even today gold is a good bet.
