Have you looked at what SpaceX promised NASA for HLS? They need to be able to launch it and rapidly refuel it with 13 tankers. They’ve already spent a few billion, by the time they can reliably launch 13 refueling tankers in rapid succession and not destroy their stage 0, we could be taking $10-15 billion in dev costs putting Starship firmly in SLS territory.

Although if all goes well they'll still have all the future starships and engines afterwards. And a system that doesn't cost 100x as much to launch.
