He doesn't need to fight anyone, like literally! Mihawk never did, why should Zoro. Mihawk holds the title but nobody challenges him, nobody cares about that title. Mihawk himself doesn't challenge anybody, he just sits there and grows cabbages.
There are other strong swordsman: Fujitora, Greenbull, Rayleigh even gad damn Kizaru. Mihawk doesn't fight against Shanks anymore because he last his arm, then why not others? Again, Mihawk is irrelevant because his title is kind of fake. And don't get me wrong, I'm not trying to trall or make fun of him, I truly mean it. If Mihawk is the WSS, then make him one, why isn't he challenging anybody? Why doesn't anyone even care about his title?

Not even Kuina did. He just shouted that at her because she was sad due to her father being a complete dick and building a inferiority complex within her.
