This not the place to go through all of economics. I am not the person to do it either. I just wanted to point out a fallacy in your 'nobody loses' statement: You are only considering the business side of the equation. To an economist, the consumer is where the numbers get added. When a consumer chooses option A over option B, there is value in that choice. It might be savings (and the ability to use the amount saved on something else). It might be additional value (Avatar is better then Chinatar). That value is the scorecard for an economy.
