right, if you know how cookies and urls work, all that can happen with zero cookies and some query parameters, like the ones google search surreptitious add on every search result.
cookie synch, It's a freaking industry standard. And you want us to believe google money cow will dry as soon as the effort they are leading goes live?
No, it is not possible to remarket at any meaningful scale with "zero cookies and some query parameters" (though Arnavion's sibling comment is correct that it can be done with fingerprinting). Would you be up for describing how you'd do it in the shoes.example/news.example/ads.example case?

"we are confident that with continued iteration and feedback, privacy-preserving and open-standard mechanisms like the Privacy Sandbox can sustain a healthy, ad-supported web in a way that will render third-party cookies obsolete. Once these approaches have addressed the needs of users, publishers, and advertisers, and we have developed the tools to mitigate workarounds, we plan to phase out support for third-party cookies in Chrome. Our intention is to do this within two years." -- https://blog.chromium.org/2020/01/building-more-private-web-...
hint: the same way attribution happened in the early days.
google sends id abc to shoes.com and id xyz to news.com. both sends those ids back to google's own adserver. presto, google knows you are seeing those two ads.
