Just because you fund your content through ads, that doesn't mean someone else can't use a different model. Sorry to be brutal, but if you can't find a viable alternative model when ads aren't cutting it any longer, maybe your content simply isn't worth that much and losing your site isn't a great loss to anyone else.
Moreover, just because you associate ads with tracking, that doesn't mean everyone else does. The most lucrative advertising deals I know about are between sites catering to particular interest groups and advertisers who also cater to those groups and make a direct agreement with the site. It takes actual work to set this up, but can be very lucrative for all concerned, particularly without any middleman ad network taking a big cut of any money changing hands. Many models from classic sponsorship deals to modern product placement approaches are based on this idea.
> All that will happen is that the tracking networks will switch to browser fingerprinting making tracking harder to control and more opaque.
That's probably going to be illegal, too.
In any case, browser fingerprinting is becoming a hot topic for all the wrong reasons. I expect near-future browsers will basically kill it as a technique anyway.
