How many successful launches do they have in total? How many did they have 5 years ago?

Elon delivered when nobody did, now it’s quite a bit easier.

One in over a decade, for $23 billion.

(And it's arguablely a failure, as the Senate is still earthbound, and likely to remain so for the forseeable future.;))

Such a ridiculous comparison. SLS started 5 years earlier and had 10-20x the budget, and it uses mostly legacy components. SLS uses existing mature engines. Existing production facilities. And so on.

If SpaceX had ask themselves, can we make a Super-Heavy of SLS class and launch it the first time, SpaceX could have almost certainty have done that.

But that not the goal or the ambition of the project.
