What you are referring to is what was said in the episode, not in the chapter. What was said in the chapter by Jozu, "Without any determination, there is no way you can hold up your consciousness in front of that man". For your example to hold true then those that grow older, such as Rayleigh, or get injured, such as Shanks, would lose some of their standing since they are not so physically fit. As we have seen some of the strongest in haki have been those that are not at their prime.
