So what? Men with guns are also the foundation of property rights, law and order, and national sovereignty; they are not an extra cost of fiat currency, they underpin the government's ability to maintain order and structure within society. I shouldn't have to explicitly point this out.

Gold is not a currency.

Untrue. A centralized anonymous payment system is technically possible, the limitations are strictly legal.
