Ok that does make sense. But what I'm saying is that you don't have to part of said clan to use a certain style, because it's what fits you, they can be related, but like an ancestor from long long ago. They don't have to be part of the same Clan to use a certain style. There are more chances that if you are part of a Clan you'd get that style, but is it really obligatory?

Oh of course. It's like the Senju Clan and he Uzumaki Clan. They're different clans from different villages, but that have the same origin. You don't have to be part of same "clan". You just need the blood of the same ancestor.

But the problem was that no one could infuse earth and water style to create wood style to the extent of hashirama since he was special (due to obvious reasons).

Fusing two Nature Transformations together is a Kekkei Genkai(bloodline ability). You can't learn it. You have to be born with the ability to use it. It's why Kakashi couldn't copy Haku's Ice Style KG, because he doesn't have the genetic ability to have it. Think of Kekkei Genkai users as mutants.
