The Poneglyph was discovered by Gol D. Roger was the only man to discover all Poneglyph, so it would be reasonable to keep a hidden treasure or whatever it is with another hidden treasure. Luffy does care of the One Piece maybe more than any other pirate in his generation because it reveals the throne of Pirate King he dwell about so much.
