That so many exceptions and alternative interpretations are possible makes "value" a meaningless term. Perhaps some day reporters won't go MEGO[1] when hearing it.
Value is just like a variable, it is a place holder for what matters. And the value of the value can vary depending on the person or the situation. It could be a positive or a negative value, a value of high importance or minimal importance. Assigning something a value just basically means you're not entirely disinterested in it.
