I don’t know if like the spoiled grain analogy.
If my stock portfolio was worth $1000 yesterday and is only $800 we don’t say the $200 was destroyed. I have the same number of stock. It may go down further, but it can also go up to say $1100 tomorrow. Is this a new being value created, or only capricious market pricing things differently?
Until I sell, there is no real gain or loss. And for the farmer, if the grain goes bad it’s not temporarily, it will never recover. This might have been a better analogy if the underlying real estate was destroyed (uninsured and fire, etc).
