You just have the predisposition (inborn talent) to activate it. Hardwork won't cut, just like you can't train yourself into activating the Sharingan or Byakugan if you are not a Uchiha/Hyuuga descendant.

The Byakugan comes from a complete different planet and therefore it is impossible to awaken it, if not related to the Otsutsuki Clan.

The Sharingan is a mutation of the Rinnegan, which in return is a mutation of the Rinne Sharingan those abilities come from the God Tree. Just like Wood Release.

All those abilities where granted to them because they owned a special chakra a.k.a Kekkei Mora, but over time the people with these abilities underwent a mutation for themselfes and so these abilities were later passed down as Kekkei Genkai.

There have been a few people who can use all five basic elements, but that does not mean they can use the KG that involved combining the five elements. Thus, I believe that having a nature KG means that you can use the specific element (i.e. Lava) and by virtue, you can you its parts (fire + earth).

Like explained above Kekkei Genkai come from somewhere, they just don't randomly show up. Byakugan, Sharingan, Rinnegan, Rinne Sharingan, Wood Release and Shikotsumyaku all have a origin. The others like Ice Release or in this case Mud Release don't. Genetics, Mutation and Evolution all follow the simple rule of cause and effect. As long as there is no 'cause' a.k.a a mutation in already existing Genetics their won't be an effect a.k.a an advanced nature.

Take the first for example, he is the only personal who can create Wood on his own (we do not count the people using his cells). It's not JUST because he combined earth and water together, but the main reason he could was, simply, he was born with the KG to that allowed earth and water to fuse into wood. Once he tapped into that hidden potential, wood came about. I highly doubt he was the only earth and water user at the time, so why is only Senju H able to do it? Because he was born with it.

Well there is Moegi, who also possesses Wood Release.
