It seems to me that digital cash systems offer humanity a wonderful opportunity, namely the possibility of money without the interference of banks and other financial instiutions. Apart from covering the cost of installation and maintenance of the systems there doen't need to be banks to be involved.
Banks create money every time they make a loan.
But they also charge interest. As any computer scientist knows interest grows exponentially. Many modern day monetary and economic systems only function through loans. Digital cash offers this possibility too.
