While that is true, I use the term in the colloquial way every reader comes to identify money — Fiat. The title is used to set the scene for everything that follows i.e. an exploration of the implication of its death.
I don’t think using one word in any way cheapens any of the assertions that follow, in fact by using the hollistic term to introduce the piece it leaves you to question your prejudices for what your assumptions were.
The best piece of writing should make you think. I’m not saying this is the leading example of this by any stretch of the imagination, but sometimes I write with the intention of leaving gaps the reader must fill in. From my perspective that expects a certain level of engagement which make you apply what you are reading to examples in your own life you can understand.
