What is "money"? "Money" is simply anything that people accept, not necessarily because they want to consume that thing itself but only to exchange it for other desirable things in the future
Surely, there can be more than one form of "money", & not all people may perceive it as "money" but that doesn't cease it from being "money" for those who are using it as "money"; I'm sure, in the past, when gold was more common form of "money", there were other communities that didn't use it as "money" but does that have any effect on the perception of that community which IS using it as money? NO! Not at all!
I, Steven & others could sell each other goods in exchange for gold, it mayn't make it "money" to others but surely for us it IS & anyone else saying otherwise doesn't make an iota difference
I'll cite your own statement :
It doesn't! As I've said, some people may perceive something as "money", others not but that doesn't change anything for those who do
