I think we are actually in agreement. You are correct that there is a fundamental argument over whether mankind is an outsider to ecosystems or not, but there is another element there, namely time! Those that want wolves in the woods are pursuing an agenda to return ecosystems to at least pre-industrialisation or the widespread settlement of the west by non-indigenous populations. In fact, those who place a greater value on the wolf than on both rural livelihoods and sustainable use conservation of wildlife resources through hunting are ahead in the game (actually, not morally IMHO)- they have got their wish and re-introduced the wolf, which is increasing and spreading. There is definitely a question here of values which is being argued by both sides, but in this case, wolf re-introduction could result in an imbalance through not providing a means for effective counterbalance - if we continue to provide wolves with food (as we inevitably will through agriculture) and don't allow sufficient control, the wolf will spread and increase to a greater population size than would have existed before man got involved (which is a paradox for the eco-mentalists)... which brings us back to how can we hunt or control wolves effectively... I hope!
