? I don't follow your reply.

The term 'money' can be anything people agree on to transact their energy over time, and in fact has been over even over just the few hundred years the US has existed. From Spanish gold to bearer bonds to US gold to Mexican silver, Confederate bucks, to Bitcoin and the US dollar.

Legal definitions have to be very precise. I don't see how one can define a fixed legal definition of 'money' in a way that holds up over time, while also not counting 'anything of value' or something silly.
