Re: Money supply
The basic problem is that money is divorced from the value of the thing it is supposed to represent.
Of course it is. Money replaced barter, and is therefore a proxy for the perceived value of everything. The determination of the multi-dimensional value of that proxy for everything that could be bartered is, I believe, called "the market' and notwithstanding certain views is far from ideal - because, I'd suggest, of the aforementioned multi-dimensionality.
