I'm one of those urban people with no interactions with wolves, which statistically means I agree with you.

Ranchers, however, are not the only ones against wolf reintroduction. Hunters want to shoot elk or deer, and see wolves as a threat to game species. Rural land owners don't want the government telling them what they can or cannot do on their own land (ie, shoot wolves). Some think it's a waste of money, for something which isn't that important.

If there were a tropic cascade as described, fewer people would think it's not worth it.
