I have DoNotTrack set and my browser blocked several tracking scripts from their site.
As for the problem, it really comes down to making money: Data is sold to inform targeted adverts. An additional requirement is that the ad company needs to know how much to pay the ad host. Also remember that ad blockers came about mostly as a result of reducing web bloat and reducing the fight for the users attention.
Nobody in their right mind would agree to this without some sensible solution in place. Servers cost money to run and content is usually not free to create.
