It's hard to check the calculations used, but couple of items - structural (40 t) and propulsion (38 t) - aren't clear. If some reductions are possible in these areas, they could save up to 70-80 t, bringing required payload to 120-130 t, which is close to what Starship is planned to have.
In other words, it's good to have an analysis; it would also be good to clarify existing questions to the analysis.
