So you just named all of the Holy Knights basically? And why were they so hesitant to engage Luffy in Elbalf and words used to suggest that they were avoiding him if he is so weak compared to them?
The road poneglyphs dont just disappear because a rubbing is taken...that's why several pirates have had rubbings of the same poneglyphs...so Luffy doesn't have to get the rubbing of Elbaph from Shanks at all...his crew could get it from Elbaph and Scooper not get in their way because of what the Strawhats do in defense of Elbaph...Luffy may meet Shanks at the spot that you said, but not for this reason...
I have not seen one thing that would suggest that Shanks is above Kaido...it took everybody and their mommas to take him down...Luffy just delivered the final blow...and let's get this straight, Shanks took down Kidd easily because Kidd was on his boat...this wasn't as straightforward as you'd like to make it... There's a reason why Shanks and everyone else avoided Kaido!!!
