"Soon" could be a factor of decades. NASA can't entirely depend on SpaceX nailing it with Starship, and I suspect the first launch with Humans on board is still years away, let alone launching to the moon.
Also, if you look closer at the SLS program, there will be replacements which will make the launches cheaper eventually. Not reusable though.

- bayesian_horse 4y agoI think SpaceX has shown that they can be, at least for Falcon 9. But it took quite a while and there is on the order of a hundred times more demand for what Falcon 9 can do than what SLS can do.
