Good point there, I guess that a bunch of people came and tried to capture/destroy the sunny (maybe even marines even though they weren't supposed to, as he is a Shichibukai and that was his last wish). Don't forget that he didn't leave the place for 2 whole years and that it's harder to defend something other than yourself, meaning that he might've had to receive some hits on purpose in order to defend the sunny, hence the damage. In addition, only his presence there for such a long time wouldn't leave him unscathed even if nobody came.
