The problem is that bad sites with horrible popups, popunders, page takeovers, random words highlighted to look like links but are really ads and all sorts of other crap drive people to adblockers. So people just install it and forget it so that sites that aren't horrible and don't totally ruin the consumer experience with ads suffer. And if a site is "nice" and doesn't put that crap on their site today, who is to say they won't tomorrow? So users never bother to turn off their ad blockers.
