I guess I am odd in that I don't find self sufficiency a foreign or impossible concept. I grew up on old family farms that dated back to the antebellum and pre-revolutionary American Southeast. Had my ancestors not been able to provide for their own needs in the eastern NC and SC swamps... I wouldn't be here. I'd say that my grandparents and great grandparents grew about 90% of their food and
firewood. But, it was also a network of family farms.... resources were shared and traded. My great grandfather was half French. He raised hogs, had a smoke house and was a master of charcuterie, very much in the French tradition... made cheese, too. He also kept
bees and supplied the entire family with
honey. My grandfather was mostly Irish and almost obsessed with replicating Thomas Jefferson's Monticello. He created an edible landscape. Nearly every square
yard of his 40 acre homestead held edible crops and landscaping. Livestock was integrated. Small ponds held fish, snapping turtles and gators. He even had a remarkable nuclear fallout
shelter, that he designed - air and
water filtration, its own septic tank, food storage, fuel storage and electric generator. He built his own house and did historic preservation as a brick mason for the state. He built and ran his own sawmill, farmed
land for timber.... invested in huge tracts. He was a giant of a man and as close to being truly self sufficient as I can imagine. Meanwhile, my afore-mentioned great grandfather and my afore-mentioned grandfather's father both owned/ran country stores in addition to farming. There were things they could not produce on their own farms.... and that did not include liquor... they had stills. So, once they realized the profits othersw ere making trading, they began small stores of their own. They both did very well selling their excess vegetables, meat and timber in those little stores. One went into building houses for others - made a comparative fortune as a home builder and land lord. The other rolled his profits into more land. Hunting and fishing supplemented the diet..... but, we are talking about families of 15 kids! People these days question whether or not they could support 2-3 on 2-5 acres..... my grandmothers cooked for small armies.... the kids all had responsibilities of helping out... and nothing was store bought save flour, sugar and a few spices. But then, another family member had a mill and ground grain "on halves" -
local farmers brought in their grain... half was ground and returned to them and the other half was taken in trade to be sold. My grandfather grew sugar cane and set up his own cane mill. Timber tobacco, cotton, fur trapping... and sometimes, liquor, provided cash money. Even doctors took meat and veg in trade for care.... but, doctors were a last resort after ever grandmother's home remedy. Do not doubt that it can be done, but it does take family/community. No one man or woman can do it all. That said, I have known hermits who did all they needed for themselves.... few people now'adays would wish to live like the, though.
