Bollocks. Easier to have good neighbors who you share with and know you are prepared to help out in an emergency situation than have neighbors who don't give a crap about helping you because you are secretive and they "think" you're living high on the hog.

If there are 10 people around you, one of whom is a jerk and will take advantage and steal you blind or strongarm you in that situation, would you rather have 9 people who don't give a crap because you're living in isolation, or 9 people who you're collectively helping out who'll stand with you. And don't give me the peace through superior firepower BS either. A good neighbor is more valuable than an AK anyday - Think with your brain. - Yes you might have 8x or 10x less "supplies" for sharing. Frankly, you'll probably not need it - or by the time you did you'd have been robbed blind anyway.
