Using that logic, gold will always and forever be a useful currency. Just like salt.

I'm really not trying to be an ass here, but because gold was valuable yesterday doesn't mean it's going to be valueable tomorrow. By extension, gold's history, or as you put it "the test of time" is a meaningless measure for its value tomorrow.

Now obviously I don't think gold will be worthless tomorrow, but I also don't think something needs to exist for thousands and thousands of years to be trusted. Airplanes have only existed about a century, yet I presume you've flown in one?
