Well, it's the New World, to even have made it that far means you either wield a powerful Devil Fruit ability or can use Haki very well, and since Haki isn't that well-known most people who made it there have DF abilities, and then learnt of Haki, to become even stronger, luckily enough, Luffy, Zoro and Sanji were all taught Haki from their masters during their 2 year training.
