They don't need to pay the mass penalty of landing legs, just some much lighter pins that stick out to the side.
The Falcon 9 landing legs were some excellent engineering, but scaled up to the size of starship they would weigh many tons (note the square-cube law makes them more unfavorable proportionally, not just massive considered amsolutely).
This would be a big deal for the booster, but it's absolutely vital for Starship itself because any additional dry mass subtracts directly from the payload (actually, it's even worse since it also increases the fuel needed for landing).
Another advantage is that it's better for reuse, as they don't have to spend hours or days restowing legs, recharging deployment cylinders and replacing crush cores.
