you are talking about "productivity", whether you realize it or not. The money in circulation and readily expendable can be expanded or contracted in relation to productivity. When it is expanded or contracted far out of step with productivity there will eventually be undesirable consequences.
Commonly, excess money is absorbed by sovereign bonds. As such these bonds represent potential, latent inflation. The servicing of bonds represents expansion of the immediate money supply to the extent it itself is not rolled into bonds.
The first order affect on money supply is credit; not routine C.B. policy that has only a weak second order effect on money supply.
I agree that "outgrowing debt is favourable compared to cuts in consumption and government spending."
A practical problem arises for Central Banks. Their policies can only have second order affects on productivity. It is only legislative bodies, ie., parliaments, etc., that can have first order effects.
