The problem is that Yoru was never ment to show that Black Blades were the end all. One Piece wasnt supposed to be this long back when chapter 50 came out.
Oda retconned the Black Blade to be something swordsman can strive for.

People seem to misunderstand what Oda was talking about... Oda said in an interview that the original plan for one pipiece was for it to be short... thats it... This means this was Oda's plan from like Chapter 1 or even before chapter 1 since Oda says he knew how one piece would end years before he even got serialised.
But from when he decided to add the Warlords is when he knew his original plan for five years wasn't gonna work... Meaning He literally could've decided to add the Warlords even as early as chapter 2 or who knows when... But the fact is, by the time Mihawk showed up, the warlords were already a thing in Oda's mind and he has said that one idea for warlords is the major reason the story is so long...
And I didn't say that Black blades are a thing swordsmen strive for, in fact I'm sure they aren't... I just said when a swordsman reaches the WSS level is when they get black blades... As in black blades are like what show that you are a contender to be WSS and really only Zoro and Mihawk ever wanted that
