What makes a true pirate in One Piece, a.k.a another rambling post

I posted a rambling Plurk about this yesterday, then thought it would be cool to hear my f-list's thoughts about this, too, should anyone be interested in sharing.

I was having some vague thoughts about common fan speculations about the future of One Piece, and that led to thinking about how Oda tends to write child characters, and that led to more general ponderings about how a "true pirate" should act according to Luffy. (And probably also according to Shanks, Gol D. Roger, Whitebeard and perhaps other non-evil pirates in the story.)
