If you don't want to think about how to checkmate maybe this website isn't for you.

Probably not, but we are talking about the CAPTCHA itself :)

You raise a good point about making captchas that target your target audience in that they aren't really designed to keep out bots, but humans who wouldn't fit in. This looks very much like that sort of captcha.

Basically, it's the internet equivalent of "You must be _this tall_ to ride".
