It’s not necessarily the same as economic value, but to say that it isn’t a concept sounds like the type of FUD that the article spreads.
Besides, it’s not as if it’s difficult to understand that, say, the economic value of food (or stocks in some business if you prefer) is something different from a currency. By focusing on whether “intrinsic value” is real or not is focusing on syntactics, without even considering the underlying argument. That makes it an incredibly poor rebuttal.
It mentions Adam Smith, Ricardo, and Marx, but nothing in modern economics.
The only other thing I found for "intrinsic value" involved investors looking at the values of companies, but that's investing, not economics.
Of course it's impossible for me to prove a negative. Maybe you could respond with a link of your own, describing the role of intrinsic value in modern economic theory?
Isn’t it absolutely obvious to any economist that “intrinsic value” is a real thing, and that the value of an apple is something entirely different from the value of, say, gold? And the rebuttal is… intrinsic value is a flawed concept?
To me it looks like someone is trying really hard to not understand the critique, and write some sort of reasoning why it doesn’t matter.
