I reject the premise of your question. You are implying that in order for the economy to grow by 4% we need 4% inflation. That's total economic nonsense. Unfortunately what you are espousing is what passes for economics education nowadays.
Not at all. The money supply is not related to the growth in GDP. Your confusion about the topic shows that you don't understand the gold standard and its shortfalls and you certainly don't understand money supply or inflation.

You make me laugh. Please, explain what causes inflation, if you know.
