Money is (or should be) like electro-magnetic waves. That is, everywhere and every-when available as one graciously flowing moment to facilitate our wants and needs within an ethical framework considerate of others and the planet.
If god is omni-present then the best and most opportune place to meet him/her is in the present moment and every proceeding present moment.
Retail sale is the ever present moment intersection of the economy’s purpose (where production becomes consumption) that must be facilitated in the most ethical way possible.
If god’s loving grace is freely given, then let the monetary paradigm reflect that with a continuous flow of monetary gifting/gracious free gifting that enables both production and consumption in the most ethical and ecologically sane way possible.
