Sorry have to disagree, you have the definition of greed all wrong. Greed is a very specific word referring to currency, currency of any kind, or in a more general sense, wanting more than you need. Like a man killing 100 fish though he only needs 20 to survive, but he ant's more money so he kills even more. it's an extreme overreaction that people often enact to fill a need for power and control over their lives. This word does not apply to some of the things you have named, not at all, as love is not something you can take too much of, or over hunt, over mine. Your analogy is flawed, so as to support a very personal belief you have in the concept of greed, a belief I do not hold with. Greed is responsible for most of the worlds suffering, and it's not any of the types of "greed" that are not greed at all that you talked it, but greed of wealth and possessions.
