"Because ads don't work on me"
I used to think like this also until it dawned on me that I have no idea where the motivations and reasons for my decisions come from. This is because they are almost entirely subconscious. And if they are subconscious we have no real way of knowing whether we are or are not influenced by advertising.
e.g., visited the Heineken Brewery in Amsterdam when I was a late teenager which was basically an advertising museum of all their advertisements going back to the 1950s. Before that day I had never drank Heineken but after that I found myself drinking it regularly for years. If you asked me if I was influenced by advertising I would have said no way. Now I'm more open minded to that possibility hence I use adblock to shield my poor defenceless brain.
