Because that's the only way to showcase him beneath Shanks in power scaling
Because Shanks fans think if Shanks cannot be strongest in verse, he will not be a great character regardless of his strength.
Cause they cannot even after MANY confirmations about WB superiority, Kaido superiorty to comprehend the idea that Shanks is beneath them. No matter how many times Oda confirms it in manga, they will refuse it and they would rather downplay these characters and discredit them, while at the same time, search for the flashiest quotes in databooks about Shanks, the twist their meaning, and THEN, say "See, Shanks is stronger"
I don't get why Shanks power being under someone else is a sin for them! they get so definsive as if he will not be a good character anymore! Weird
