Sure, breaking a window is easier, but that triggers an alarm and arms the home defense system. If, OTOH, the thief subverts the home automation system, not only can they open the door and disable the cameras, they can instruct the system to pipe the anti-intruder knockout gas into the biolab/hackerspace where you are burning the midlight oil, working on your revolutionary chimpanzee/cheetah hybrid pizza delivery servant. The thief is then able sneak in undetected and steal your zygotes and tissue samples. Worst-case scenario, they'll take a kidney as well. Yours, I mean. This is why it's so important to have physical safeguards in place, like the mechanical stops that keep the home defense cannon in the foyer from being aimed away from the front door. And obviously bulletproof metal shutters.
