A couple of things. I am not sure that they need a use case for Starship's "bigger" capabilities. If a Starship launch ends up being much cheaper than F9 (like Musk claims), then SpaceX will be using it to send payloads to orbit even for things that don't require a 1000 tons to orbit. That's a win right there. As for what payloads will utilize Starship to the max...NASA is already thinking about it. https://arstechnica.com/science/2022/05/spacex-engineer-says-nasa-should-plan-for-starships-significant-capability/ https://arstechnica.com/science/2022/05/spacex-engineer-says... Yes, it will take a while, but they'll get there eventually. Meanwhile, Starship can do the NASA missions to the moon and whatever F9 is doing today.
