It’s not the cost of the fuselage itself, but the infrastructure to build it and the throughput with which they can build them. If you want to increase the number of rocket launches, you need to increase the number of rockets. We will always launch them as fast as we can build them, and it’s probably cheaper to develop reusable rocket tech than it is to build a single additional rocket production facility. It makes every production facility afterwards that much more efficient. It was a great economic move if your goal is to increase the number of launches as quickly as possible and make spaceflighy routine.
