A tie is so much more than just a tie. To Luffy, a tie is easy access.
Luffy wants to kiss? Grab a hold of Sanji's tie and urge his head down. Quick sweet kisses are pressed to the chef's cheeks and throat. Maybe even a bit of a marking bite just above the height of his collar.
Luffy wants attention immediately? Give Sanji's tie a few soft tugs to drawn his focus. It always earns Luffy his hair being ruffle. The tactile stimulation brings a smile to his face and boost his energy levels as he giggles.
Luffy feeling particularly territorial? Grab Sanji's tie and a firm tug. Dragging the cook onto his lap. One of Luffy's hands gripping the tie like a leash as his other hand sits possessively on the blond's hip. The captain's nose pressed to the cook's warm throat while glaring over Sanji's shoulder at potential threats.
Luffy thinks Sanji's working too much? Grab the silk tie and slip the knots free. Tie the chef's hands behind his back with the incredibly soft material. Just hoist the bound chef over the captain's shoulder and carry him to the calm of the aquarium room for an afternoon of snuggling and watching the fish.
Luffy can't stop fidgeting while cuddling? Just stroke the smooth, soothing texture of the tie's material while snuggled in Sanji's arms. A calming fidget toy that keeps Luffy from running off before either one has had enough cuddles.
A tie is never a blindfold. Never something to make Sanji feel trapped and frightened in the darkness.
Law is Like This™ post-timeskip because he stopped smoking weed. So he could focus on his plan. Poor guy forgot it made him so much more laid back and I think smoking just one (1) weed would have made it alot easier for him to go through the whole Pirate alliance thing.
Look at him he went from guy who dresses like he's delivering hash and gives you freebies in exchange for a slice of pizza to guy who will implode into a million pieces if he says his coffee order wrong:
