I am sorry but Luffy choses the journey not the other way around....he made the choices to do what he wants to do...he made the choice to go to enies lobby, marineford, alabasta, wci, wano....he had other easy choices and paths to take...destiny just guides him based on his will, not the other way around....for example, he took the path of rescuing robin from enies lobby even when it is impossible and robin was "destined" to die if Luffy didn't make that choice....then "destiny" helped Luffy in the form of sea train/gallela workers etc.
