Yeah, there are many things that can or have been money. Many have different attributes. Database isn't core to being money to me. This is the same problem you have when you claim bitcoin can't be money because it has no "intrinsic value" like gold supposedly has. Can you touch bitcoin? Nope so I guess its not money like gold or sea shells are money. I don't think its a helpful analogy. Sounds like the blockchain hype stuff to me.
