It is true that most of the oxidizer mass could easily be save by relying on atmosphere. However, what would happen to the atmosphere if it is relied on as oxidizer? If launches are made as frequently as the lack of predicted expense permits, there will be DEFINITE side effects: Since N is a major component of the atmosphere, and S, C, and H appear in higher than trace amounts, we can wind up with lots more nitrous oxide, nitric oxide, nitric acid, sulfuric acid, ammonia, various hydrocarbons, and worst of all, free radicals, not to mention freon-like molecules. What happens? We increase the amount of acid rain, reduce the ozone layer, reduce the amount of oxygen in the atmosphere, and generate more petro-chemical byproducts. Chew on that!
