He never said, "the people most receptive to ads"- he said, "the perfect demographic for expensive stuff".
He is suggesting that people who have they money and desire to pay for something that makes their lives a bit more pleasant are the kind of people advertisers wish to get their ads in front of the most.
Not all advertising is about clicks- tv advertisement was built around getting information in front of eyeballs.
Letting people opt out of advertising for a fee, will just remove the small minority of people who would never click on ads anyway. A win-win.
