He needed the marked kunai because there was no trace of his chakra in the destination he wanted to go. The mark is made with his chakra. With the SG/FTG example, what I'm suggesting is that he can teleport anywhere because by extending the reach of his chakra through the natural energy, this can sort of act like a remote marking.
