The only reason starship hasn't involved human sacrifice thus far is that they haven't put humans in it. It remains to be seen whether the engineers will manage to make something usable from musk's 'Cybertruck - space edition' fever dream.
Because we haven’t seen a single re-use of a starship yet nor any significant payload brought to orbit, or the orbital refueling turn around and launch cadence necessary to even achieve 1/10th of what Musk suggests is “possible on paper”.
Super-heavy is being wasted on a potential dead end 2nd stage in my opinion.
A single RS-9 engine -- one of five used in the SLS -- costs more than an entire Falcon 9 launch with payload, taxes, and profit!
Starship is similarly frugal. Its construction is simpler, it is made of cheaper materials, it uses a cheaper fuel, etc, etc...
