Cause its absolutely trash writing that Zoro cant even get some chaps about his past ? In the land of swordsmens ?
Cause that means the backstory of our boy will be revealed later into the story and not just what everyone had predicted.
Later means better/ more important.
Zoro could return to wano for whatever reason?
His mother/father could be someone really important and saved for later?
All the parallel between him and Ryuma never completed..
Oda has something in store for zoro and the mere fact that this is later into the story, it automatically becomes better for me.
