Is there money to made by marketing services to people who don't know any better? Certainly!
There are countless examples of services that no one needs, but that customers line up to pay for. In fact, many of these services make realizing the desired outcome more difficult (not to mention more expensive). So, how do you sell something that no one needs or necessarily wants? Focus on a false sense of fear and offer to "handle everything."
The anecdote: A notice from Company X, which I have never heard of, explaining my obligation to update a legitimate administrative legal matter. Clearly, my time had come. I paraphrase: "So many horrible things can happen to you if you don't address this matter. Luckily, we can handle everything for you. Just pay X to us and we'll take care of it."
There's nothing exciting, inspiring or genuinely likable about a business model that relies on ignorance.
