We can't spend all our time worrying about the uneducated masses and their improper application of "security".

They can only learn when faced with something breaking in some cases.  Then the policy can be reviewed and the reasons "why" will be considered.  If they're truly uneducated and incapable of this, we can't bend over backwards forever for the unenlightened masses.  At some point you have to let it break, just like why I'm not using a 2500 anymore at home.
