The thing is, bad guys have guns too. You can't really defend against many thugs if they take you by surprise. Somebody could just wait somewhere near you house and snipe you, it's impossible to detect everything all the time if you leave your house or go near windows even once. And bad guys can use even explosives to break into your house.

Don't get me wrong though, since guns are extremely useful for defense and most of the bad guys aren't very tough. Surviving without a community in a serious scenario is just impossible.
