While I agree on most points with you, ads still is what pays for us to have free internet.
Think how popular email or Twitter or whatever would be if it was a small price to pay each month.
That doesn't mean that can't or will not change in the future. Steemit is a good example of a service not only without ads but that can pay for valuable content.
In the meanwhile, ads will be here and big companies will try to fight the adblockers.
