I feel like Wikipedia may be misleading me in a subtle or egregious way.
The very first line of Scarcity is: "Scarcity is the limited availability of a commodity..."
It does, of course, helpfully provide that "a commodity is an economic good or service that has full or substantial fungibility..."
My question, then, is: Does it really make no sense in economics to discuss the scarcity of non-fungible goods?
(In the interest of full disclosure, my interest in the subject is mostly related to thinking around whether post-scarcity has anything at all to say about non-commodities, but that's quite a different set of questions.)
