I don't really thing this approach to fulfilling your dietary needs really scales well in today's society. You can view all of the civilisation of man (i.e. the establishment of cities, interconnected communities etc.) as a way to ensure specialisation of skills.
It not only doesn't make sense (economically) for a computer guy to go hunt down his beef but it's also incredibly difficult from the logistical point of view. I live in a big city and the nearest food I could go and shoot is probably miles away. If I went out to try and hunt some food over the weekend the odds are that I'd go hungry!
I can't help but to feel like this is not a good PR move.
And, remember that killing your food is a sign of aristocracy. Native Americans were not called "noble savages" because they seemed neat or something, but because they hunted and adorned themselves with pelts, which is something that only European aristocrats did.
Personally, I prefer butchering my meat myself because of the low-quality of butchering in many mass-production facilities.
