The US already has what you call an ad police: for decades, it has been unlawful to make false statements in an ad and to accept any money for advertising (or endorsement or sponsorship) without making it plain to the viewer which parts of the content are ads and which are not.

Since the US Federal Trade Commission can smoothly enforce the second of those two rules, what makes you think it cannot smoothly enforce an outright ban on ads? "Smoothly": you seem to have been unaware that the second of the rules I described existed, and you probably would have been aware if the enforcement had yielded anything deserving of the name "kafka land".
