I find the subjective argument too abstract for practical use. All the subjectivity in the world must come to head with reality and how it can be enforced in reality. I am of the opinion that logistics wins wars, and labor theory of value, with its flaws, is able to provide a sense of direction for me to act on. Maybe I can bet on an asymmetry of needs with someone wanting to raise a family with me if I was unemployed and they did all the work, but I have the impression that a partner would appreciate me being able to help with the work too.
