SpaceX has from the very start had a philosophy of break things quickly.
NASA has QA and reports and assessments for everything and it costs a fortune. $4Bn a flight for SLS. SpaceX builds, breaks, changes and tries again. That is the same rational for the first 3 Starship sub-orbital flights and it is the same rationale for the Super Heavy Booster. It's actually cheaper in the long run. So successful in fact that something like 90% of the mass lifted to orbit this year will have been done by SpaceX, not in the US in the World.
