All money is is a construct of a "great" (depends how you view it ha) accounting system & without the accounting side (banks) normal currencies simply couldnt exist as currencies seeing as most of the money thats currently in existence is a fraction of whats actually out there. seeing as its all been digitized already by the banks. The banks have been trying to create a cashless society since there conception. the less cash there is and the more digital transactions means its easier for them to concentrate control. so the paper that was written was basically trying to state the need for a trust system that would facilitate the transactions of digital currencies. at least thats what I got from it anyways.
