Another use of "fungible" in a way I can accept:

The issue of corporate downsizing has provided many examples of the
shallowness of the media. Typical was a seven-part series in the New York
Times in March 1996 entitled "The Downsizing of America. " The articles
focused almost exclusively on the displacement and adjustment of workers, but
said little about the benefits to consumers and other workers. This passage in
the first article is about all the reporter had to say about that: "Some contend
that through these adjustments American companies will recapture their past
dominance in world markets, and once again be in a position to deliver higher
income to most workers.

Others predict that creating such fungible workforces will leave businesses
with dispirited and disloyal employees who will be less productive. And many
economists and chief executives think the job shuffling may be a permanent
fixture, always with us, as if the nation had caught a chronic, rasping cough."
