I hate sheep.
My son bought his first house over a year ago. It's just inside the city line in an OK neighborhood (not great, just OK). He bought in the Spring and one of the first things we did was put in several raised beds in the back yard. He was fortunate to get a double lot, so his yard is pretty big. That first season, he grew far more than he was able to preserve and gave a lot away to neighbors, and they were grateful. This past summer, we noticed three or four of his neighbors started their own gardens, and they shared some of what they grew with my son.
Granted, a backyard garden can certainly help a lot with lowering food costs, but it's not a homestead. It's a start and it's more than what most folks are doing. Imagine not spending several thousand dollars on lawn care services to maintain that golf-course-pretty grass, and instead make that yard produce food. That would help enormously!
Back to sheep. No one is stopping anyone from seeing to their own needs. People who would rather have the government use force against others who are NOT a burden on society are idiot sheep, and they can't see what's coming. They will still starve, but rather than blame the government - the entity that screwed everything up in the first place - they would rather blame those who are self-reliant.
