> get a pot of land and grow your own food
Rejecting industrialized society is actually very expensive
Artisanal food for hipsters is always going to be a market. People are willing to pay a premium for locally or regionally grown produce, fruit, eggs and meat.
However, it's a risky business so I'd only recommend getting started if you either (!) are FIRE already even after sinking 3 million bucks into purchasing land and machinery as well as constructing all the buildings or if you join a cooperative/union or if you got experienced farmers in your family.
Everything else - especially following "prepper" influencers shilling books and holding more public speeches to shill for said books than they are actually working on their farm - is a recipe for certain disaster.
If in doubt... first try raising a few dozen chickens in your yard as a starting point.
"industrialized society" just rejected 160,000 sofware engineers this year. other industries are no better. you are either wage-slave barely making it. or getting laid off, as those people are not needed.
