I mean, they have to go load and unload the camera. They have to pick up a gun or bow and at least walk out in the field and wait for the thing to come around, then they have to kill it and drag it back to the car. A damn dear can weight a bunch, man. It's real, physical effort. Then they have to wait for the deer to cure and be butchered -- it's the opposite of instant gratification (if you can believe that!). Hell, a lot of guys butcher their own kills. I'd bet you can't carve a Thanksgiving Turkey worth a damn.
On the other hand, you walk in to an air-conditioned mega-mart, Visa Debit Card in hand, and buy pre-killed and prepared steak. You have no connection to the steak -- it could just as easily come from Korea as Kansas, for all you know. Wherever it's from, you can bet some poor sucker got paid too little to kill the cow for you (and he was probably illegal, if the steak is from America). When a beef recall is issued, you have to rush to your freezer (on the next commercial, of course) and see whether or not you've poisoned your family.
And, while on a day to day basis, survival skills (including hunting) may be wholely un-needed, did you not notice the situation in New Orleans (and much of the South) after Katrina? A bunch of sisified urbanites crying for Uncle Sam to come save them, because they have no clue how to protect themselves, or provide for themselves, in the absense of what is really a fragile social system. Safety is an illusion, and I'd much prefer to live in an area full of self-sufficient hunters and survivalists than in the middle of an urban jungle with people who are going to have to rob me for a can of Chicken Noodle Soup if the mega-mart closes down for two days.
