There’s a difference between what Luffy was doing versus what Zoro, Hyogoro and the Scabbards do… Remember… Hyogoro himself said what Luffy was doing was different from himself… Didn’t stop Hyogoro from still having AcOA
the point remains, If Hyogoro and the scabbards have ACoA then Zoro has it too… If they don’t have AcoA then you can make the argument that Zoro doesn’t have it too… Because it’s both repeated and demonstrated that whatever Hyogoro and the scabbards have IS EXACTLY WHAT Zoro has
