Except you forget that by your own argument, Kaguya has the "power of the Sharingan". In order for Indra, then, to have a Sharingan, the Sharingan's power must also have been in Hagoromo. Regardless of whether Indra was born via chakra or genetics, this has to be true, since Hagoromo can't pass on a power he doesn't have.

But your theory says that only the tomoe Rinnegan has the Sharingan's power, which Hagoromo didn't have, meaning that in your theory, the Sharingan either A) is a derivative of the Rinnegan (which is a theory that requires genetics), or B) the Sharingan popped out of nowhere.

Which is it?
