I don't really think that's fair. The context of that discussion would have been vastly different. We've know for a long time now that Luffy didn't beat BM during that arc and the moment she had her den den mushi call with Kaidou, it was almost a given they would meet up. So when BM eventually popped up in Wano, it was a matter of chapters when they would come face to face.It was a pretty big debate during WCI. Most argued Luffy would beat BM in that arc, some of us argued he wouldn’t and the story was gonna lead BM to intersect with Kaido.
I personally theorized they would link due to a lot of thematic and visual similarities between them and that Caesar and the SHs would ultimately be the linchpins.
So I find it a bit misplaced to emphasis on that discussion while I sincerely doubt there were even any people left who believed the opposite
