2. A unit of account refers to the numbers that are used to describe the specific assets and liabilities that are reported in financial statements rather than the units used to measure them. I've shown you 3 accounts denominated in gold. 4. A standard of deffered payment is the function of being a widely accepted way to value a debt, thereby allowing goods and services to be acquired now and paid for in the future. My transaction with Credit Suisse fits it by definition as I'm using gold in ounces to value a position I'm vesting it into.
Again just because you haven't used gold in these definitions does not mean its not being used by others with a bit more wealth than you.
