I explain why this is a valid counterpoint in the second sentence of my post: Today in the press we have a more or less clear distinction between advertising and content, and I think if we banned advertising it would create an unintended incentive that could lead to the destruction of unbiased journalism as we know it today.
I think the distinction between advertising and content is a lot more blurry than you realize. The majority of 'news' articles begin from some company's press release, product placement is common in fictional worlds, and journalists frequently self-censor to avoid displeasing advertisers.
