Doesn't history show us you just get both?

You pay to get into the movies, then they show you adverts before the film, then the film includes paid product placement of cars, computers, phones, food, etc.

You watch youtube ads, to see a video containing a sponsored ad read, where a guy is woodworking using branded tools he was given for free.

You search on Google for reviews and see search ads, on your way to a review article surrounded by ads, and the review is full of affiliate links.

No. "Opaque ads" are usually heavily regulated out of existence by government legislation.
