There may be some temporal confusion here. Gen-Z rates of homeownership has stalled out over the past year or so. Prices are no longer rising like they once were, with fears over impending decline, so the desire is not what it once was. It may be fair to say that the narrative has shifted to "too expensive", but as they loaded up early when prices were rising at unprecedented rates there is a big head start at play. They don't have to buy any more homes for a while to maintain the lead.
