Scary only for flippers and scalpers who only care about short-term value of the card.
When true collectors like something, they just buy it if they deem it is worthy.
Even in other hobbies (Pokemon TCG is not my only hobby), I even have bought things way above that amount simply because I adore it. (Even now I do buy vintage Pokemon and MTG slabs at current prices!)
Without a care of its future investment value or whether people will sought-after it in the future or whether it would decline in popularity and value.
Not “diseased in the soul” but YOLO and these feed my soul.
