I actually think that Hashirama is the only wood release user because its turns chakra into the source of life. Now, call me crazy, but i think that might stem from his whole powerful life force, stamina and Yang chakra which literally "breathes life into form" (basically, the Asura deal). Seeing as how Kurama's Yang chakra caused the wood release to bloom, idk. Also, Jugo's not a sage mode user because Kabuto wasn't using his power to enter it, but to supplement it's time limit it infinity. Same with jiraiya, he's not "passively absorbing" natural energy, but having the toads help collect it for him and mix it. And The is the "God of Shinobi" we're talking about, I'm sure he could learn to use sage mode himself. He might even be its creator, but that's a stretch.
