The waste does not at all stem only from different risk tolerances. SpaceX launches NASA astronauts which means that they also need to comply to the same standards. Pork barrel projects like SLS is the real reason why everything NASA does is so expensive and late.
The statement that NASA would have achieved reuse eventually is weird considering that NASA still exists today, 35 years later, without succeeding.
