I've always thought of scarcity and FOMO as different things, at least from a product marketing standpoint.
Scarcity: There isn't much of this thing, so I need to compete to get it. I will prioritize it more highly. There is a scale of desire for this thing. If I believe I need it in the future rather than now, I may defer.
FOMO: 0 or 1. I am going to miss out on this. Is it important to me? If it is, I will prioritize all my resources to get it now. If I believe I need it in the future, I will act now.
Totally agree. Maybe if OP phrased it as “Urgency” instead of “Scarcity”, I would have agreed. But these are two distinct concepts that just happen to cause similar outcomes. Almost similar to a concept of an “incorrect” or “false” abstraction in SWE land.
