Im going to hold your hand when I say this. It is not realistic to expect yourself or your family to be able to survive solely off of food you have foraged or grown in a garden. People with more knowledge and experience have tried and failed. What do you think happened to all of those communes in the 60s? Most of them failed. Famine and malnutrition have been constant companions to humanity until industrialized farming and food supply lines came along.
It feels like a uniquely American capitalist take to assume these traditions will make you completely self sufficient. You need a lot of people, a lot of time, a lot of knowledge across a lot of subjects, and a lot of luck to provide for everyone's nutritional needs.
So should you even bother trying to be more self sufficient with your food? I argue yes. Foraging and gardening are fun and will teach you so much about many things. They are deeply rewarding activities that can supplement your diet. There are herbs I haven't bought in years because I grow my own. There are dishes I can only make with foraged ingredients because I can't get them in stores.
You may not have the power to do everything, but that doesn't mean your efforts are wasted. Getting 5% of your nutritional needs from food you have grown or foraged, even for a season, is a massive accomplishment.
