The beauty of the Starship design is that if it works, it makes landing and taking off anywhere we want to go incredibly easy. You don't need a special lander module, complex docking manouvers, to replace disposable heat-shields, or anything. You land the Starship, and launch it again -- as is, no moving parts.
Earth's atmosphere and gravity are much heavier and stronger than either the moon, Mars, or even Mercury. If you have the regulatory controls to re-enter and land on earth safely, it's trivial to do it on any of those destinations.
It's still an incredibly hard challenge, and not might not work. But if SpaceX successfully reaches orbit and lands on earth with the Starship, landing on the moon and coming back is going to be an absolute cakewalk.
