While i agree that Sanji's attempt to get the Straw hats of the hook won't change much since they'll go up against BM eventually, you forgot that there's still someone Sanji has no way at all to protect: Zeff. Even if he manages to break free from the bracelets, manages to reunite with the rest of the rescue squad, even if they manage to beat Big Mom which is pretty damn impossible  right now unless Bege, Jinbe and the Germa move against her simultaneously, there's nothing he can do to protect zeff once the vinsmokes send the underworld after him and probably every human on the Baratie, unless you expect a quick journey back to East blue to be an option.

Aside from that, he's been forced back into a world and life that he never wanted to be a part of and that never considered him to have any worth, a life that caused him immense trauma during his youth. He's been forced to realize that even with all the experience and training the past 13 years have given him, he's still as powerless against the terror of his family as he was back then (even though this is only due to the threaths and explosive bracelets). Being forced back into an emotional trauma that way is known to make people act similarly to how they acted back when it was inflicted, and what Sanji went through would strain anyone's mental fortitude.

I'd say he's waiting for an opportunity in a currently hopeless situation. It's all he can do right now, since there's no way for even luffy and the rescue squad to beat BM as things are right now. And between Jinbe's resignation, 2/4 sweet commanders being beaten, Bege's plotting, the germa's arrival, the rescue team scattered all across Totland and Luffy fighting a damn army, things are certain to get interesting before long
