Overall it is a good picture.
the picture offers an alternative that we should seriously examine.
I am in no way a specialist in economics and commerce.
Since the proposed approach is strictly pragmatic, Natural law is only mentioned.
The film does not dethrone the status of gold as a currency, but we can forgive this.
What comes to mind in answer to the view expressed by one of the interviewed- about the nature of money itself and the supposed inevitability of using FIAT currencies-
IMHO, Fiat currency could be re-imagined, to be a record of expressed care; with the re-design of current bills into a shape of palm-size Rose Petals (propose same colors).
this could theoretically work after a long de-doctrination.
