You can only (legally) deduct business expenses, not just all expenditure.

Say I create a business that receives $2000/m in contracting revenue instead of personal 1099 income. What if this business then acquires a property with a $2000/m mortgage and in turn rents that property to me for $1/mo. As all revenue is consumed by expenses would the business not be taxed? It seems like there has to be a reason why this strategy can not be used to avoid tax on all personal expenses?
