The prevailing money system has brought humanity to the brink of disaster in many different ways. It is the money system that defines how our economies work and has set them on an unsustainable growth-oriented trajectory. Today it is the "money power" that rules the world:
I have argued that control of money and exchange mechanisms is the key structural element that determines the distribution of power, and that it must be the main focus if any degree of community empowerment and self-determination is to be achieved. A money monopoly, whether in private hands or government controlled, is inimical to freedom and equity.
In order to realise a new monetary paradigm, money-as-we-know-it needs to be "depoliticised." This can only be accomplished by the separation of money and the state. Under the current arrangement the banking cartel creates money as debt and charges interest on it while governments get to spend as much as they want without regard to tax revenues. Legal tender laws and banking regulations endow the banking cartel with the exclusive power to issue money (as debt), which we are forced to use (through legal tender laws). The collusion between political power and financial power is the root cause of the mega-crises facing humanity.
