None of the LTV hold up. For a start, it predicts that people won’t ever trade. That’s quite a big flaw because, you know, people do trade. Theories of value predicting people won’t trade was a big problem by the time Marx was young. His one doesn’t solve the problem at all, but well, it wasn’t a problem anymore when he published.
The family of theories of value that predict that trade happens are called “subjective theories of value”.
