why yes he has, starship has been test flown and landed, just need to test the booster, get the FAA out of the way. continue development. SLS cant even get out of the VAB to 39B for a wet dress rehearsal

This is the step that NASA dreads because it heralds the advent of multiple daily Starship launches with 100-200 tons to orbit each launch.
