Should you buy an ingredient that is disappearing from stores?
Scarcity explains less than people think.
Possibly. An ingredient may disappear because of changing tastes or supply chains, but some declining products still offer unique value.
People often assume disappearing products must be inferior.
The hidden mechanism is market evolution. Consumer tastes, logistics, regulations, and trends reshape which ingredients remain visible.
Imagine an ingredient loved by older generations but rarely purchased by younger consumers. Its decline may reflect changing lifestyles rather than declining quality.
A second-order effect develops because scarcity changes perception. Forgotten ingredients sometimes return years later as discoveries.
People often think markets eliminate bad ideas. Sometimes they simply forget good ones.
