I'd whitelist a true advertiser who ditches tracking entirely and focuses more on advertising content relevant to the page it's going on instead. Chances are if I'm looking at some Python programming page or server setup tutorial I'd be more inclined to click on ads relevant to the page as opposed to a creepy ad of something vague as heck that I looked up on Amazon 5 years ago that Amazon really wants to sell, or whatever.
I really would love to see advertisement companies that are less focused on tracking and more focused on ad placement that's relevant to the content it's going on, and hey sometimes there's no relevant ads for content and that's cool too, but at least show anything generic or close enough at that point. Also advertisers who don't do pop ups or annoying ads (that I swear could cause epilepsy on some users) are also good stewards of the online billboard market.
I'd be fine with "visitor count" type of "tracking" as long as it's just that, as far as how many per country / region. No following users around the web, aka no cookies needed. Then you could have a page for advertisers to choose sites to advertise directly on for themselves.
I'd happily attempt a startup/side-project that offers an API for non-tracking advertisements, but I don't think there's space in the market. It'd be very difficult to compete with the existing incumbent advertisers.
minor correction: creepy ads for the things i already purchased two weeks ago. brilliant use of ad targeting spend by companies i already gave my money to
