This is terribly confused.

Economics is the study of scarcity. Scarcity comes in many forms: land, attention, materials, time. (It is not the study of money, which is a common belief of those who have not thought about what money is. Money is merely a fungible token claim on resources, not the resource itself.)

You could also believe that the study of physics is just the study of business, because businessmen operate in a world governed by physics.
