This chapter was a large amount of information placed at once. As for Luffy choosing to fight with his handcuffs on, He clearly demonstrated an ability to use some of his strength when he was lifting those blocks which shows that not every once of his strength comes from his devil fruit. I know some of the fans assume that without his fruit powers he would be nothing, but I always assumed that he would find a way to become as strong without it. I actually think that Captain Kuro said something to that effect back during their fight, that Luffy has strength to go with his fruit. I can see it being similar to Goku's gravity training and his training with weights, but I can also see it as similar to other circumstances in anime as well. I know some people might find it foolish, but it is good to know that Luffy is taking advantage of situations like this to become stronger for the future. As for his haki, I would think that being in a constantly weakened state would make it difficult to concentrate. I have seen characters have similar issues when starving, or sick. He should be able to use haki as a principle, but it could be that the handcuffs are making him feel weak enough not to concentrate. It could also be that he has been using it and used it up too quickly. We didn't see how long this rebellion has been going on, but clearly it has been happening long enough for Eustace Kidd to escape. I wonder what he plans to do now.
