What good is a lander if they cancel the rocket that is supposed to

Because Falcon 9 Heavy would be cheaper than SLS ?


Except Falcon Heavy (not Falcon 9 Heavy - you've been corrected on
this before, Mayfly) can't do the job.


If they end up building a bigger lander, why not send just the lander
and service module to the Moon and back. How difficult would it be for
the lander to enter Earth orbit upon return and say dock with ISS so
crew can catch a ride in a dragon back to Earth?


Because that wouldn't work?


If they build a bigger lander, isn't fair to state that the capsule
becomes needed only to re-enter Earth's atmosphere ?


No, it isn't fair to say that.
