I read her book, it's quite good and makes good points. I studied economics and her points make sense. There truly is a big value hole, intellectually. Our current default is actually not a theory of value at all, it's a hand waive that allows us to not get stuck in a deep conversation about what is worthwhile.

Of course the problem is that any theory of value like the labor theory has massive holes as well. That's why the current subjective value theory is not really a theory: it's not wrong, it's a placeholder.
