Besides, Senju have arguably just as powerful if not more powerful life force than Uzamaki.

You need both affinities, that's it. Life force will help, but it helps everything else too

I get where you're going, and I appreciate the comment, but I believe you are misunderstanding what I mean. I'm also doing this under the basis that Naruto is a reincarnation of Asura Otsutsuki. What you described about every Uzumaki having a shot at naturally is off, since none are the reincarnation of Asura. Descendents, yes. However, only Hashirama and Naruto are the reincarnations of Asura so far shown in the series. So other Uzumaki gaining Wood Release couldn't happened.

As I also said in my theory description, having Earth and Water Release affinities will not under any normal circumstances give Wood Release naturally. Looking into the Kekkei Genkai Page of this Wiki, we can see that a Mud Release exists. As such conditions for Wood Release to be gained naturally would be: Having an affinity to Earth and Water Release, and being the reincarnation of Asura (although I did not mention it properly in my description. And for that, I'm sorry).
