Sure, now train all people to use that. And then tell them how to edit their hosts file(or to install a firewall) to also block tracking embedded in apps or in the OS. And when the OS vendor goes around the firewall and the DNS by using other technology then tell the users to buy and setup some fancy router and when they invent some other tech then what ? Much simpler, make tracking without permission illegal so everyone can benefit not only the tech people and the ones that can afford extra routers, VPNs or other tech solutions. Also not sure if private mode is 100% safe.
