Agreed. Normal non-technical people let friends have a look at their computer, and it is often a surprise for both that passwords can so easily be seen. Theory is one thing, but there is IMHO also a practical "don't make it too easy" factor that should be considered. As the saying goes, sometimes "opportunity makes a thief".
According to his logic, something like a post it note stuck to my monitor, containing all my passwords, is just as easy to read as Google chromes password file, so there's no benefit in trying to hide the post it note.
