There is nothing stopping you from using gold as payment. But its not anonymous, if you want consumer protection then you need a contract (thats how gold is traded, and has been for many many years) You don't want to physically exchange gold, because verification of gold's value is super hard. In low volumes proving that you have the correct volume and purity is very difficult and expensive.
