I have thought of this often and each time, I come up with the anwser of YES! I have three freezers full of food, a pantry full of canned goods, we have our own property, lots of timber (For cooking and keeping warm).  We have seeds stored for three yrs. garden (so if we were to have a failure--it wouldn't be a total washout). I have honeybees, plum, blueberries, blackberries, dewberries, fig, apples, grapes, pecan and pears that produce well, now. I have my chicken coop being built right now.. And I have several hens lined up and as many roosters as I want. Our property has quail, dove, turkey, deer, rabbit and way too many guns and ammo , two small ponds stocked with bream, bass, catfish and other fish.  We have enough space for all our children and grands --three houses/trailer and two spaces for nice but little apts. if they need a place to live. We have lots of older nice hand tools-saws etc.
