isn't this the mentality that's caused us to require fifteen safety stickers on a simple ladder?
No, it is the exact opposite.
Stickers and security awareness training and all this nonsense are attempts to put the responsibility on the user by telling him what to do, instead of handling the responsibility yourself by making sure that your product is safe.
As with all things, there is, of course, a limit. You cannot (with current technology) design a power drill so that it will work on a wall, but not on a hand. And if your user knows the master password that will destroy your company then he should be told to keep it secret. But you should also ask yourself if you really need such a gaping security hole or if you couldn't compartmentalise things better. Or if the power drill can be designed so that it only works if the user has both hands on the machine, to at least reduce risk.
