If chakra is as inheritable as it is.

Doesn't that mean Sarada's reserves are supposed to be around tailed beast level? Think about it. When Kaguya ate that chakra fruit, her chakra skyrocketed and her children were born with insane chakra too. BUT, there's indications that a good chunk of the chakra Kaguya contained was exhaustible in the sense that she couldn't replenish it through rest and such akin to Naruto and Sasuke's Rikudo chakra.

Not much different than the Yin seal that allowed Sakura to have more chakra than an RSM clone despite having exhausted her initial reserves if you ask me.
Now imagine that Yin seal's chakra and mutiply the amount of chakra by 5 for the 10 years she had to store chakra opposed to 2. That's Sarada's true mother, the Yin seal.

If that were the case hashirama's son/daughter would have been reputable for something.

That's about talent and Ashura descendants mainly, and it makes it clear you don't inherit always.

OT: the chakra becomes a part of your makeup so yeah especially of you inheirt the gene that produces it. Sarada needs to be nerfed. I dont think the story needs somebody who solos for the sake of it with monstrous chakra reserves to boot.

Kaguya's chakara could replenish like everyone else's. She wanted to absorb Naruto's and Sasuke's chakaras because according to her, all chakara belonged to her. In other words, she wanted to absorb their chakara for the sake of claiming what she thought belonged to her, not because her chakara doesn't replenish.

As for Black Zetsu telling her to preserve her chakara, that is simply because amenominaka uses a lot of chakara. It is no different from how spamming bijuudama would use up alot of Naruto's chakara.
