The SLS is not $3b per rocket. Those numbers, just like the numbers everyone trotted out for the Space Shuttle, are NASA's manned spaceflight budget divided by the number of launches per year. It's not an accurate cost for the SLS, you don't come up with the cost of a SpaceX launch by taking into consideration their whole operating budget. Even your Starship cost is inaccurate by half, a single Starship launch can only get it to low Earth orbit with just enough fuel to land. To get anywhere interesting a Starship needs to refuel in-orbit, a capability SpaceX has yet to demonstrate even at the small scale. So every Starship launch needs a second buddy launch to refuel in orbit. The SLS is not a perfect launch system but it's actually flying right now. Starship is still years out and requires unproven and as-yet undeveloped technology. It'll be interesting when it flies but it's a lot of undelivered promises at the moment.
