Cash is not an investment. Cash is a wealth store.

When you get down into the details, they're all just "things you can own" and the categories like "investment" and "wealth store" start to look very made up.

Cash is a medium of exchange, not a wealth store. What wealth do you store if it doesn’t even keep up with inflation?

I didn't say it was a good wealth store. ;-) But yes, it is a medium of exchange, too.
