I'm not going to claim that all externalities are priced. There is certainly a lot more that we could do. But many of them are. The cost of the calories, the tools, the training, the property, and the marketing are certainly all priced.

But let's just say that you priced all of the externalities perfectly. In this hypothetical example, can you really make an argument that all of that adds up to more than, say, 100 dollars?

And if you can't, then you still have a lot of "value" to account for.
