>> Like why bother with the trouble of setting this up if I can just print a photo and have it unlock? The question is - who are you trying to protect against? Like, personally I'm worried about someone stealing my laptop. In that case, it's extremely unlikely the thief would have a photo of me to use to unlock the laptop. Yes my wife or my friends would have access to pictures of me in high enough resolution to print and use to unlock it - but I'm really not worried about them breaking in.
