but you have to understand WHY the current system is riba...
it is riba, cuz gov can issue more currency and gain wealth relative to everyone else WITHOUT doing anything for real. They can just sit there and print more money and spend as much as they want and do nothing and make free money for themselves at the cost of the entire nation.
but if you can stop currency issuing and keep m1,m2,m3 etc constant, now have currency without riba.
