Why did Boruto inherit the Jougan?

With all these evidences, it seems Jougan represents the pure Chakra originated from Hagoromo and Hamura’s combined power. Boruto inherited Jougan because of his bloodline from Hinata and Naruto, not because Toneri or someone mysteriously gave him the eye.

Is Boruto a descendant of Hagoromo and Hamura?

No. Not for those reasons. He has Hamura’s because the Hyuuga are descendant from Hamura, but not exactly from the Otsusuki clan from the moon. Just like both Senju and Uchiha are descendants from Hagoromo, but one comes from Indra and the other from Ashura.
