Shanks didnt raise a finger during the entire Chapter 1 situation. Remember. With the bandits. Lucky roo and Beckman cleared up everyone and shanks only saved luffy coz he happened to be the one to find him drowning.
The only three times Shanks actually gets involved directly when his crew is around is Akainu Mihawk and when Blackbeard tried to challenge him with his whole crew.
Now. Do you think Kid is a big enough deal like Akainu or Mihawk where Shanks has to step in? Or do you think Kid presented his whole crew and Shanks actually got shook and decided he also needed his whole crew to match up with Kid's crew? You think Killer faced Beckman, and Heaat faced Lucky roo and wire faced Yassop and Kid even had someone who could face Rockstar. Is this how you believe it went? That Beckman alone couldn't just beat all of Kid's crew together by himself?
Okay. Sure. either Kid has a crew that actually squared up to Shanks' crew so that Shanks would decide to 1v1 Kid or Kid himself is just around Akainu or Mihawk threat level that Shanks decides to fight Kid directly despite his crew being around.
This is how Shanks has operated and this is how strong you think either kid or his crew are. okay
They were lowly scumbag bandits who were kidnapping a kid.
Kid would show up, go "fight me", and Shanks would fight.
I mean Kid would have been a top commander leveled character, so either he or like ben beckman or lucky roo would have to face Kid.
I don't see Kid showing up, challenging Shanks to a fight, then Shanks sending someone else out to fight, especially if Kid wasn't doing anything like taking hostages. Shanks would absolutely take challenges.
Also there is the theory that Shanks is Kid's father.
I think Kid defeated some allied crew members of Shanks, broke into the territory, challenged Shanks, Shanks accepted, 1 v 1, no crew members fighting, Shanks crushed him and took of his arm, Killer and the others got ready to fight, Kid went "no, we're leaving" and didn't instigate things further, then took resources and stuff from Big Mom and eventually formed the alliance so that he could go back and defeat Shanks, then Kaidou showed up instead.
Oh and wasn't it implied that Kid infiltrated whole cake island and took a copy of the ponyglyph from big mom?
No, beckman couldn't defeat Kid, Killer, Heat, and Wire. Ben Beckman is reasonably the weakest yonkou first mate based on how kizaru essentially shat on him like he was trash.
Killer is around Zoro leveled, so just below yonkou top commander leveled, Kid is higher end top commander level/yonkou first mate leveled. Heat and Wire are probably like middle trio leveled.
