Money is such a broad name that encompasses anything that could be accepted for a means of payment on goods and services. Now, not all money are still useful in present times, like the cowries, the manilla and the rest of them from a time past in Africa. These are still regarded as money but, most have no value except being displayed in museums.
Now, money cannot be regarded as an asset, not all money I mean as, most are subject to inflation and many other influences mainly from the government as they are the issuers. Assets aren't something you use in an everyday expenditure and that's very much what is the business with fiat.

Bitcoin ad Gokd perhaps could fit in but, not so much with fiat currencies and still, bitcoin haven't gotten a general acceptance by the masses.
