I believe SHs Dreams will achieve more than just satisfy their Personal Desires
Just like Chopper's Dream will make Doctors Obsolete, i believe each SH will make their Roles Obsolete
Meaning Chopper will create World without Sickness, Sanji will create World without Hunger, Jinbe will create World without Racism, Nami will create World without Poverty ... etc. So Zoro will also end up creating a World where anyone can become Strong (EOS OP needs to prevent cases like Hiruluk, Kuina, Fisher Tiger, Bell-mere ... etc)
So WSS Zoro will be opposite of Mihawk who is Bored & can't find Fights, Zoro will continue to fight anyone who wants to challenge him & will strive to keep getting Stronger so that no one can ever Surpass him
I believe Zoro will remove Death & also give the World access to a Place where they can Train Infinitely (Similar to Dragon Ball Z)
Actually i believe that's how Mihawk became WSS, He has access to Infinite Training thanks to his Clairvoyant Eyes, so He seems like chilling but He is actually processing Non-Stop Training somewhere else (Similar to Vega Records but for Combat instead of just Knowledge)
So i believe EOS Zoro will keep Fighting for Eternity & He will be main attraction of every single Fighter, similar to how anyone who wants to Eat would go visit All Blue
