The GP's premise was that wanting things is bad because the "thing" in question is generally "nature converted into object we temporarily use and discard", leading to environmental devastation. It's not the same as "wanting", say, to spend time with friends and family. I would additionally add that "wanting" is not good, in general. It's unavoidable, sure, in the same way that pain is. But to take someone from a state where they do not want anything, and convert them to a state where they do want something, is to lower their happiness. Unnecessarily inducing a state of dissatisfaction in someone should be categorized similarly to causing them pain. You have lowered their well-being.
