But its not about Humagears and Humans being the same. It is the recognition that both have unique qualities both positive and negative, and most importantly a place in society.

The notion that Humagears are "less" than Humans on the basis that humans created them is pure narcissism. If you don't understand that, think about any time you as a child disagreed with your mother about something. She brought you into the world, but it's not fair for that to be held over your head for eternity is it?

In the show, The fragility of human life was, as you correctly intuited, used as a way to diminish the worth a humagear's life (because hey you could just bring them back), but the show argues that that doesn't diminish the impact Humagears could have on others and the things they could create (entertainment, fine art, music, etc).

Being able to be brought back as a duplicate

- To a Human, it cheapens life, which somehow discredits Humagear accomplishments.

- To a Humagear it is just a way of life, even seen as an advantage over humans.

The endgame scenario doesn't rely on us treating her death as a human death, it relies on us believing that Aruto treats her death as a human death. For all intents and purposes she was dead to him.
