Your describing a situation where trust is lost. If trust is lost, how does the merchant know you really have gold in the vault? For that matter, even if you bring gold to the merchant, how does the merchant quickly test to ensure the gold is 100% pure and has not been cut with some other metal, or that your gold is not just gold plate? The modern world requires trust. A breakdown of which will result in anarchy. Food/water/guns will be much more valuable than gold.
