...If money is a pure bubble, than nearly every financial asset is a pure bubble. Why? Simple: because most financial assets entitle you only to a stream of money. A bond entitles you to coupons and/or a redemption value, both of which are paid in money. Equity entitles you to dividends (money), and a share of the (money) proceeds from a sale of the company's assets. If money has a fundamental value of zero, and a bond or a share of stock does nothing but spit out money, the fundamental value of every bond or stock in existence is precisely zero.
That's a weird way of thinking about the world. It would mean that the size of a stock bubble, measured in percentage of terms, is always and everywhere infinite. It would mean that the size of a stock bubble, measured in absolute terms, is just the price of the stock - that Google's stock now has a bigger "bubble component" than Pets.com's ever did, simply because Google's stock price is higher than Pets.com's ever was. If money is a pure bubble, this must be the case.
So it's a weird way of thinking about the world...but is it correct?
It seems to hinge on the definition of "fundamental value". Usually we define "fundamental value" as the (discounted) amount of money you'll have if you hold on to an asset. But if money has no fundamental value, then this is zero.
So what is "fundamental value"? Is it consumption value? If that's the case, then a toaster has zero fundamental value, since you can't eat a toaster (OK, you can fling it at the heads of your enemies, but let's ignore that possibility for now). A toaster's value is simply that it has the capability to make toast, which is what you actually want to consume. So does a toaster have zero fundamental value, or is its fundamental value equal to the discounted expected consumption value of the toast that you will use it to produce?
If it's the latter, then why doesn't money have fundamental value for the exact same reason? After all, I can use money to buy a toaster, then use a toaster to make toast, then eat the toast. If the toaster has fundamental value, the money should too.
So does saying "money is a pure bubble" mean that toasters have no fundamental value, and that therefore, the price of toasters - or, indeed, of any non-consumable good - is a pure bubble? If "fundamental value" = "consumption value", it seems that it must mean exactly that. Now we are into a very weird way of thinking about the world....
