I also wonder if somehow we're trying to seriously reduce advertising what that does to land of the internet where the users of the internet seem to choose / want "free" advertising based products. I'm not convinced folks just suddenly pay and upending that entire economy maybe a serious net negative.
Equating "things I don't like" with "negative externalities" does not seem like a helpful framing for this discussion. I personally like traveling around the world and eating avocados, but they have substantial negative externalities. I personally dislike watching ballet or eating mushrooms, but they have minimal negative externalities.
Advertising may very well be something that the author dislikes AND that has negative externalities, but the point of a Pigovian tax is solely to apply a price commensurate with negative externalities, not the dislike.
> you to some extent want that activity to occur otherwise you've got budget issues
Perhaps, which is why he mentions "freebates", and why I find revenue-neutral Pigovian proposals like the "carbon-fee-and-dividend" so compelling. The primary purpose is not revenue, it is to ensure the correct price on negative externalities so society can rely on a free market to solve tricky allocation problems.
