People still don't understand.
When Shanks met WB in a clash that divided the skies, WB and SHANKS were under a ship.
Considering what was said in SBS and databook, WB could use his 3 types of HAKI, while keeping his illness contained, by medical equipment, considering the fact that SHANKS can damage / cause damage, with his sword, even before touching the your opponent's weapon (in general), and WB, is also capable of doing this, since we saw the same collide with ROGER, which means that, being on a ship, they had to restrain themselves.
Kaido and Big mom were the same, we know that KAIDO can make his club reach Napoleon without even touching him, and Kaido did not do it in the CLASH against BIG MOM, because he is inside ONIGASHIMA.
In both situations we know that 1 of the users can make his weapon not even touch his opponent's, which is KAIDO and WB.
