I have to say that I agree to an extent. They shouldn't, "set it and forget it" as the dude from Ronco says (I love infomercials), however, they realistically wont bother to learn the intricate details of securing their system(s). I compare this behavior to password policies that are too strict. Because most end users gravitate towards ease, after a certain point, they'll end up taping their strong password to the back of the keyboard. The same goes for securing their system. We have to remember that these people don't see computers and technology in the same light as IT professionals. To the end user, everything is magic and always referred to as a "thingy".
Give them enough information (presented in laymen's terms) to allow them to use the computer for the purposes they need.
my 2 cents
