Don't the invested dollars poured into infrastructure that won't yield gains represent a loss of value? Especially if the same investment could have been put to work somewhere more fruitful.
It's (1) a loss of expected value (2) misspent resources.
You spent $X to buy RAM chips, expecting that you could produce $Y with it. But you didn't. So you (1) failed to realize the expected value $Y, and (2) misallocated $X, which in hindsight you would have used differently.
Again, that's all learning that future expectations do not match reality.
The decision/action happened earlier, and is separate from the realization. Attributing the material loss to the realization is misplaced.
You have exactly same assets as before. The businesses of which you are a fractional owner have the same fundamentals.
But other people won't trade other assets for yours at the same rate.
