if anarchy were to occur i wouldnt supply myself i'd armed-stick up everyone near me...no joke
seeing as how you would have to live in a city to make such a crime pay off i doubt if you'd last 2 days...and those of us living life outside of the cities would be laying in wait for people like you...seriously!
if you wish to survive you'll need a new plan. thieves and other neer-do-wells will be the first to go. perhaps cooperation might be a better way to live longer and thrive? i think so...
