> Ask yourself: is the average person noticing holes in fences and trying random doorknobs… probably not.

Yes. Especially kids, and by extension, parents of kids. Also teenagers. And people without means. And clever competition. And people with above-average levels of curiosity. And yes, criminals too.

I'd describe it from a different perspective: most people assume their problems are obviously solvable through an available service, and if they aren't, then either they need to delegate it to specialists or the problem itself is invalid. The minority of people who are into solving problems themselves are, at a high level, hard to distinguish from small kids, teenagers, and criminals, because they all share the characteristic of straying from the journey down the sales funnel, as they're pursuing their own goals and are not interested in getting to the bottom of that funnel.
