After a recent conversation with Arindam Basu, it occurs to me that there is yet another method of explaining the Douglas Social Credit approach to our financial and economic systems for the benefit of newcomers. This has to do with the notion of constraints. There are natural constraints, i.e., constraints that are built into the very nature of things and are of a physical or metaphysical nature, and then there are artificial constraints, i.e., constraints that arise merely because of arbitrary (or not so arbitrary) human conventions that can be, at least in principle, abandoned, replaced, or altered at will.
