But that's not the definition of a patriarchal society from the sociological perspective that Elle uses - particularly not as distinctly different from an egalitarian one. Most cultures have gender roles, although what those are tends to differ from culture to culture and at different times in history. Modern foragers have gender roles, although they don't necessarily adhere very strongly to them, but that doesn't change the fact that they are egalitarian cultures.

The quote I cited to you was from a colonial woman who had gone to live with the Natives and described how much more personal freedom she had there, including when and who she was to marry as well as the ability to end a marriage if she wanted to. No-one controlled her, and certainly not any men. Yes, men had more power and status, but women still had plenty of autonomy and also some influence in many cases. What she is describing was not a dominance-based hierarchy with lots of social stratification and wealth disparity which includes a society where men control and have power over women - that's what a patriarchy is. Ergo, it was not a patriarchal society. It was an egalitarian one, just as all forager bands were until about 6-9 thousand years ago.
