Why is this even a discussion?
My browser talks on behalf of me to a server talking on behalf of a company or other person. If loading a web page was a literal discussion between me and a company, it would go something like this:
Me: "Hi, I would like to request <x> information from you."
Company: "Okay. But first, can I interest you in some special offers from our affiliates?"
Me: "No thanks; I'm just interested in <x> today."
Company: "Okay, here is <x> information."
Ruling that Ad blocking should be illegal would be as absurd as ruling that saying "No thanks" in the above conversation should be illegal. And if it ever becomes law, it will be one law that I will never adhere to.
