Granted that this is true, FH right now does not have these capabilities and SLS has already done it. For all the amazing success of FH it's completely the wrong vehicle for a mission like this, which is why Starship exists and IMHO is the future.
The point is the mission was designed to prop up SLS, not designed to actually be worth doing. A base on the moon could be supported with FH, and much more cheaply than one supported by SLS.
