Different design processes and NASA has to appease Congress who likes to cut funding if a rocket blows up.
But the Design-build-test-break-redesign-etc process that SpaceX uses is cheaper, quicker, and gives more data.
And blows up real good
Look how long it took to develop SLS and how much money was spent, and then how much each launch costs. And the moment Starship is complete SLS will be obsolete.
