SLS still gets $2.5B every year, around $30 billion total so far (at least billion every year since 2011) and cost 40% more than they said it would: https://www.planetary.org/space-policy/cost-of-sls-and-orion

Starship being able to otherwise fund itself except for the Artemis R&D project is good for the government.
