Although that is the conclusion Zoro comes to in his fight with King, Zoro throwing away his individualism for Luffy's dream was never set up as a problem anywhere throughout the story, with the exception being in the King fight as well, which makes Zoro's dilemma seem pretty artificial. If there was set up building to this climax, of Zoro losing focus and missing opportunities to get stronger for Luffy's whims throughout the Post-TS, it'd be more organic. Instead, Zoro's resolution of equalizing Luffy's dream with his own is rather hamfisted extremely haphazardly to the point that many don't even catch that Zoro even changed his viewpoint on how he prioritizes his and Luffy's dreams once again, and frankly I can't imagine this really changing how Zoro acts throughout the rest of the story, especially since Obe Piece is in it's Final Saga. It's too little too late.
