So you only derive your opinion from an appeal to authority? Whatever the economic experts say. Demand for money is constant, not always increasing. Unless you mean by population growth than sure. The demand is only higher now because it is new and hasn't reached 8 billion people yet. Supply is also not deflationary. It's constant. Technology is deflationary. Prices for things always fall to marginal cost of production. Marginal cost of production always goes to zero. What's needed for a stable economy is a money with no supply change.
