Then you have to look at this like that are samurai the term and culture only in wano ?? Yes there tons of swordsman out there but only wano is called samurai
they talked about haki but Zoro didnt learn 100 percent wanos swordsman technique he learned the basics from them the rest was his own creation otherwise everyone can buy a book about bushido and can call himself a samurai

Kin'emon learned Ryou and Oden's made up 2 sword style AND MADE UP fox fire style
Zoro learned Ryou and MADE UP 3 sword style.
So again, be specific. You keep dancing around this.
Just say it's a nationality thing.
You keep trying to make a distinction between the fighting code as if there is a clear visible one.
For example, Bushido is characterised by intense Loyalty.
Isn't that like Zoro's big character trait. Intense loyalty?
Bushido is characterised by intense honor both in and out of combat. Zoro is introduced performing an Oden act of honoring a ridiculous deal to help a little girl and when Zoro is in combat with Mihawk he doesn't accept turning his back as an act of swordsman pride.
Bushido is characterised by self sacrifice for one's superior. Zoro and Kuma.
Oda has Vivi literally call Zoro "Mr. Bushido"
Im telling you, there is no difference between Zoro's general character and Samurai. You would have to nitpick small thing to find any differences.
So let me say it again, Just say it's nationality. That is literally the only argument you can make.
