I don't get the argument. I don't think something being magic will stop humans from exploiting it. At the end of the day intelligent people are great at coming up with excuses as to why they should do something bad. "Just chop that one tree down, its in the wrong place anyway" "Just kill that one dolphin, its old anyway" when taken together these add up to bad outcomes we dislike. Much better to discourage / fine / ban all tree chopping and dolphin killing and let select professionals remove sick trees and dolphins.
