Advertising is just psychological manipulation. Any argument that there's "good" advertising that respects the target and is merely informative... well, maybe there is, but it's overshadowed by the other 99.9% of the garbage.
Implementing this feels impossible, though. There would be disagreement as to what constitutes an ad. I disagree with the author that advertising isn't an exercise of free speech; I think that would be a huge roadblock in any country that enshrines free speech rights.
But man, that would be great.
