Fly to Mars (or anywhere else in the solar system), land, unload passengers and cargo, refuel, take off again, fly to Earth, land. Refuel and start loading for the next flight.

That's the end goal. And since not all bodies SpaceX may want to land on have a comparable atmosphere to Earth, parachutes are not part of the plan.

This isn't the vehicle that's going to do all that, but they have to start somewhere to build the tech that eventually will.
