That's false right there - The grey wolf doesn't belong in WA, MT, ID, WY. It has never been here - And the Timber Wolf, while endangered, never left here, so reintroduction is a misnomer... But you are right about the 'no upside' thing.
You’re point is well taken and I agree, I just don’t go into that part of it every time I post on this. The Canadian grey wolf is a larger and more dangerous animal than the American Timber Wolf.
Maybe the grizzly bear should be reintroduced in California where they used to roam. Maybe start with the hills of Malibu? After all, it is the icon on their state flag.
