I'm not likely to bother blocking first-party images or other content so-delivered. Odds are I won't be bothered enough by those to block them, or if I am I'm more likely to abandon the site than to start blocking that kind of ad on every site.

The problems are the tracking and the ad networks that kinda treat both the viewer and their site-hosts as consumable resources, but that sites can't realistically avoid if they want/need ad support, because that's where all the money is. Break the ad networks, break tracking (and I mean legally, in both cases—tech means for blocking are doomed, IMO) and ad money won't go away, it'll be redirected to less-awful ways of delivering ads.
