Whether he fights kaido or not theres obviously a difference between luffy and zoros current situation
While it's taking luffy a while luffy is still making his way up to kaido. With sanji and jinbe there to help lead him there and conserve his energy
While we haven't seen kid and law in a minute they are more likely than not doing the exact same thing and slowing making their ways up
Zoro unlike them is already involved in a separate story line thats going to keep him busy from progressing for a hot second
- We know queen wants to take him out when he was looking at his bounty
- We know big mom is making her way to their direction
- We know there's a chance orochi might be alive
- King fighting zoro is still possible
He has to do something
If not he just coulda been with luffy
