Not a lot of "love one and other as you love yourself" there...
Back on topic, I don't see how a decentralized network is actually possible in the absence of a global currency. The need for an interface back to Fiat really does imply some sort of distributed network to me as I don't think it's realistic to believe that individuals will become FX traders -- way to much risk. Can someone give a simple transaction based example -- theoretical -- of a decentralized crypto-currency network that doesn't ultimately devolve back to a distributed (nodal) network?
