No its not! The interest rate is the discount rate for buying future goods in exchange for present goods. The natural rate is the equilibrium price of the time market, not money market. price of money is a Keynesian fallacy.
There will be no shortage! The interest rate will rise until demand equals supply. What is you complaint here exactly? The people have not saved enough tomatoes and cheese?
You are clearly missing the point here. This is not about redemptions, nor is this about bank runs! This is a clear indication that you are misunderstanding Austrian Capital Theory. This is about investments that do not equal real savings (I don’t want to repeat the previous explanation of what real savings means). This is about a mismatch between credit and time preference. If you increase the money supply via credit markets, you will misdirect resources into higher order goods by distorting the natural rate of interest, which does not correspond to consumers time preference. There is no place for MV=PQ in Capital Theory. If you value yourself as one who adheres to science, you cannot use a mystical equation.
You are in no position to take this Rothbard vs everyone else tone, for you are clearly confused about basic Austrian theory. We can thank Horowitz and White for that. They are brilliant in many respects but they have deeply blundered on this matter.
