Yeah but imo Luffys only issue was he didn’t know it was possible. The second he did, he accomplished it (sure slightly crudely at first, but then way stronger after he ate food) Zoro found out it was possible but couldn’t figure out how it was done. He had to try and fail for the entire fight with Sommers.
Let alone Zoro and Sanji couldn’t even really awaken their CoC without intervention, but Luffy could.
I think Zoro and Sanjis struggles being so focused show just how talented at CoC Luffy was.
