> Every other currency is either backed by men with guns? 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. > transactions are reversible (fiat) Cash payments are not reversible. Reversible payments are also a feature that nearly everyone wants. > spend a roughly proportional amount of resources securing it (e.g. gold). Gold is not a currency. > that's only because it can operate with less assumptions (no identities), which I see as a feature Untrue. A centralized anonymous payment system is technically possible, the limitations are strictly legal.
