In principle: If you pirate movies or the GPL, the legal system comes after you. So no, not completely broken.
But that's my point: Those industries have taken the path of serving the subsegment of the market that won't break the law/contract. And maybe that's the answer for website advertising, but adblockers are a one-time install and look like less effort than pirating (for movies) or obfuscating (for GPL). So good luck if that's your business model.
In both of your example cases, there are actual legal protections. In the case of a content farm, they're making content available for _free_ without a terms of service in the hope that people visiting them won't be blocking the ads they're also serving. Show me the content farm that makes users agree to a terms of service requiring ad viewing, and then your examples make sense.
