As I said, only a matter of time. The author of the article on the Catalhayuk adds a necessary caveat; "Hodder cautions, however, against drawing too many conclusions about a society so distant from our own. Current theories about Çatalhöyük’s level of gender equality may one day seem as quaint as Mellaart’s belief that its residents were goddess worshippers. “Interpretations will change, different ideas will come along,” Hodder says. “What’s important is leaving a detailed set of data that people can play with, test new hypotheses against, and mine endlessly.”
Absence of evidence for a phenomenon is not evidence of its absence. The claim of militaristic invaders from the north begs the question...how did they become hierarchical?
The Catals seem to have stayed egalitarian in possessions and wealth, possibly their technology never produced the amount of surplus needed to maintain a warrior class to impose hierarchy. The author suggests that these inequalities DID develop and suggests them as a possible cause of the eventual societal failure.
I see accumulated wealth as a necessary precursor but not a determinate. In North America the Pacific Coast people developed technology successful enough to create surplus, and a creative way to alleviate the inevitable inequality of wealth that arose called the potlatch. Though this did not necessarily eliminate hierarchical structures in their societies ( they still held slaves and the impoverished were sometimes not allowed to participate) it seems to have tamped down actual violent conflict over resources. https://en.wikipedia.org/wiki/Potlatch
Beliefs and traditions can be strong bulwarks of values, sometimes for long periods of time. They can also vanish quickly. Our own traditions of the peaceful transfer of power, of election losers conceding often before the final count is in are not enforced in law and now under assault.
It's easy to imagine how the cultural values of a society could persist for centuries past the conditions that produced them, and also easy to see how they could be swept away as technological/economic realities reached an inflection point.
