It seems to me that a major factor that mitigates against sustainability is the bunch of economic theories that dominate us.
If we go back to an early definition of money as, "a token for goods and services", we realize that the planet can only sustainably supply a finite amount of goods and services per unit of time, then it follows that if there is no inflation, only a finite amount of money per unit time can be used.

Financial institutions make money simply by writing credit, what this means is that they create tokens for goods and services that don't, and can't exist, this based upon the assumption that the supply of goods and services is infinite and all that is required for a viable economic system is to control the money to pay for them.

I would submit that any viable sustainable economic system will have the following principle at its base, that, the only money that can be hoarded is that that is not used in consuming the sustainable supply of goods and services available.

This essentially establishes the principle that goods and services are finite and only a upper maximum can be supplied per unit of time, whereas money is an abstract concept that can take on any value we choose, and if we create excess amounts of it we can just cross it out and renormalize our accounts, the exact reverse of the current situation.
