Regarding the rural food that metrosexuals plan to take: we’re ready for you. For the humble few who plan to grow it, you’ll need about 2,000 pounds of fertilizer, 10 gallons of diesel, 2-3000 seeds and about three months of canned food per acre to start or you’ll have to survive all year on summer’s weeds.

You don’t seem to understand. In places such a Costa Rica, food grows wild, nearly everywhere, right up to the ocean. There is no need to steal food in the countryside with such a small population & wealth of free food. Why risk stealing when you can gather your food for free?
