You are talking about systemic or inherent value. A tree in the wood capturing carbon and producing oxygen obviously is valuable to us all. They are talking about economic value. How can a spcific economic actor make money from transactions associated with that tree.

A common mistake. In a neoliberal market economy nothing has value unless it can be arbitraged. For 'natural' products that means that unless someone can prevent 'free' consumption of that benefit, and contain and charge for access to that benefit, there is no value.
