I don't believe Wood Release is something Hashirama alone has had, I think Kaguya/Ten-Tails can use it too and hell maybe even Hagoromo/Hamura and I think Asura inherited it too, meaning Wood Release is an Asura incarnate thing.

And the reason why Naruto doesn't have it might be simply that Minato and Kushina's genes/chakra simply overwrote Asura's chakra too much.
