This is just going to be another arms race.
From a website owner's perspective privacy plugins are ad-blockers.
I run a website that has one sponsor and their ads aren't blocked by privacy tools - because it's just some static HTML text, link and an image on the page. So I'm not sure what "local ads" you are referring to.
(In much the same way, I don't see a whole bunch of ads because I use a Flashblocker ... but ads don't have to be flash)

If that's how a website owner thinks, then I'd say they have a very narrow idea of what an ad can be.
Ghosterly and Co blocks those common third party solutions even when run locally. E.g. from the Ghostery source:
"type":"analytics",
…
"pattern":"\\/piwik\\.(js|php)",
or "type":"ad",
…
"pattern":"\\/adpeeps\\.php",
