The people who think they are "survivalists" haven't taken theft into account after the break down of governmental and social structures or they are just being idealistic dreamers.
Let's be realistic! When the Zombie Uprising comes, it's not going to be a cute fun camping trip people. I'm going to go into your zombie momma's house, smash her Precious Moments Collection out of spite, scoff at her instant coffee and steal her hooch. That's how I'm going to survive.
So while you are packing your water filtration kit, and rolling up your sleeping bags look behind you, what's that noise? Yeah, that's the 4 zombies that are about to eat the Abercrombie & Fitch hat that you call a brain.
Me? I'm tipping back some rum. Gotta leave a little room to push the rag in.
