We’re just too ignorant to be trusted with levers of questionable power over such a complex system.
@vvanders: I hate to break it to you, but raspberries aren’t native to the Americas either. Calling one species invasive while ignoring the plethora of other species which have no significant history in a place is just a word game. In fact raspberries can be classed as invasive, but so what? Raspberries got about a 100 year head start on the starling, so they’re grandfathered in? Feh.
