Non subjective evidence? I gave you actual sources and actual real world people who use the concept in the "real world". Actual sources and actual people is not subjective evidence. These are things that directly contradict your statements.
>I'm familiar with value investing. It's not clear to me why you believe the occasional success of value investors is proof in inherent value as a universal economic truth.
Occasional success? I gave you a person who has year after year of success for around 50 years. There is no quantitative way of expressing this unparalleled success rate as "occasional success." Also what is a universal economic truth? There is no such thing. Economics is a soft science which consists of a bunch of varying theoretical models and schools of thought, none of which (like all science.) can ever be fully "proven" as a universal truth.
I presume you are actually asking whether or not intrinsic value is valid school of thought in the academic landscape? It is. See the economic definition of intrinsic value in the link I posted above. Or google it.
>I haven't claimed anything about value other than that it's subjective- that doesn't preclude, for example, a company's perceived value relying on a number of other subjective values.
Perceived value is subjective and therefore according to your definition a logical interpretation of value. There are many cases where the "Perceived value" of a company is different from the the sum of its parts or other "subjective valuations" in which the company is built upon. This leads to an inherit contradiction in the subjective theory of valuation. Meaning that a company has two different values: The subjective value of the company as a whole and the subjective value of the company as a sum of its parts. A contradiction indicates that this is a highly flawed way of thinking about valuation.
>to leave is childish and the hallmark of a troll.
You insulted me and called me a troll. Am I being the one being childish? I am simply stating facts. If you leave saying we have no subjective common ground when I only offer hard facts. The only logical conclusion is that you are trying to exit the conversation because you have no hard facts to prove your point.
