This goes far beyond a "working definition" in that it encompasses literally every game that unlocks content in any way. /Some/ distinction is needed to differentiate a "loot box" from every other game mechanic.
It would be like using "a metal object that can harm people" as a working definition of an assault weapon. If the definition also includes ladders, cars, and push-pins, it's far too broad to be useful in any discussion.
