I’d like to see evidence of the opposite happening to be honest.

gladly. despite the high value of faberge eggs, no more are produced. despite the high value of epipens, enough have not been produced to make them affordable to all who might want one. of course, this doesn’t actually quantify demand, and i’m still not sure how that can be done.

edit:

despite no demand for iphones in 2004, they were subsequently produced.
