My original comments were in regards to the poster’s assesrtion that wolves are not needed in the lower 48 states and that the “ecosystem” did just fine without them for years. That’s a pretty broad statement.
Hunting is just one tool in the toolbox for management of natural resources. It is not a panacea, any more than releasing wolves into certain regions based on incomplete and in some cases faulty science.
Wolves don't stay in their "certain regions," as we've seen. They make a lousy tool because they are very hard to control. OTOH, name one place people won't hunt.
