I foresee tech companies creating paid and non-paid versions of their products. If you don't want your data monetized, please pay $50/month for Google Search, GMail, Maps, and YouTube. If you are okay with the value exchange of ads and free services, then you are opting into a mutually agreed upon arrangement with no compensation.
This would create a weird paradox: Advertisers want people with disposable income. People without much disposable income get really targeted ads (they won’t pay for the privacy). People with disposable income pay for the privacy service and don’t get ads or get poorly targeted ads. It then becomes more like traditional ads that get broadcast to everyone. So the policy shoots itself in the foot.
Video streaming (and music streaming though not as much anymore) also have premium versions without ads.
I think people are willing to pay for an "ad-free" experience on some services and still see ads elsewhere.
