I think you're underestimating how much it costs to maintain a global, distributed application that has a lot of money running through it 24/7. You'll need legal teams to write up you contracts/TOS, and keep them updated in the face of changing laws and regulations. Site reliability engineers to keep everything running, and dedicated development teams for bug fixes and unavoidable application changes (say you realize there's a bug exposing customer data, you need that fixed now, not whenever you can find a contractor). Don't forget phone support. When you factor in the cost of running the delivery app, plus about $10-15 per hour to pay the driver, which has to account for driving to the restaurant and to the customer, I'm not sure how much cheaper food delivery can be. It's already a competitive marketplace, and there's even small, regional apps, but I haven't seen any that are significantly cheaper in general (excluding things like temporary specials, deals with a restaurant chain, etc...)
