To put it in context, Artemis did many fully destructive tests but typically on the ground. Artemis had and spent an overhaul budget that was likely close to a hundred times that of what SpaceX is spending in today’s dollars.
And even better representation, all the fully destructive tests of SpaceX have carried out have costs less than a single successful shuttle launch. And it has a much larger payload.
Even with the destructive tests, of which are planned this way, not only is SpaceX is far cheaper than any past space program, they are advancing fairly rapid.
