So your last paragraph description of nuclear family is basically what 80 percent of world population would have looked like in our own world in 1300s. Most of the characters we see in books come from people in the elite, warrior, or religious(magic) classes. Through out recorded human history with some variation gender roles have been consistently similar because of biology and survival needs. Variations of gender roles has usually occurred because of unique differences in the environment or some major change like disease that drove an adjustment. I would argue that the freedom to explore gender identity hasn't lead to more happiness or stability among most people. And for most of us it's not really something we seek out for entertainment. Especially among the demo of people who watch shows on streaming services. Rafe went with probably least likely to succeed option on a service that sucks at fantasy. Amazing it lasted 3 seasons. And the tragedy was what it might have been.

There is not enough of a television audience to support a big budget feminist queer fantasy epic. On top of all the other more objective issues the show was still catering to a small proportion of people that routinely watch TV on streaming. So Go woke go broke is actually not a bad summary for show being canceled.
