> All currencies are going to start off at $0, being worth nothing. That's far from guaranteed. Gold started off as a commodity, worth much more than nothing. It ended up being a means of exchange because its properties are suitable: it's highly valuable, easily divisible and durable, and other stuff I forget now. But those are the reasons it started being used as money. In fact, it's possible that nothing that will be widely used as a currency in the future will start off at zero value.
