O.O holysh** batman that makes perfect sense, there simply was no barriers back then
everyone could travel to other worlds freely, but since the growing threat of darkness (notice how i didnt say heartless) they (they could be anyone, maybe the worlds themselves, afterall worlds want to protect themselves as all thats why they guide the keyblade in the second game) put up barriers around the worlds, eh perhaps i'm wrong but oh well it was a shot
i think because they are keybladers they will have a unique way of travel, maybe each of them will have their own gummy ship, that would be fun but you dont have to do that stupid rail shooter instead you just fly to worlds. or maybe back then keybladers have found these useful paths that only a keyblader can use
