Just to sum up what everyone is saying here.

Oda follows the "Surname Firstname" order. And he uses some western names such as Edward Newgate but changes the order. Normally, Edward (firstname) Newgate (surname) but for Oda Edward (surname) Newgate (surname). Obviously Oda was inspired by western names for this and others characters BUT he wanted to change the order and he did. Nothing "dumb" and no "mistake" here. That is what he wanted and that is what he did.

NONETHELESS, Oda uses the "Surname Firstname" order regardless. So going back to the original comment here by "fandom user": it is not Luffy D. Monkey but Monkey D. Luffy. Monkey is Surname and Luffy is firstname. Now as for the fur, I don't get how the Gomu Gomu no Mi can cause that.
