The way I see it, a farmer is one who operates a farm, and a farm is an area dedicated to the production of food or other plant or animal products, but that's irrelevant. We can use the word "homesteader" if you prefer.

Life as a homesteader sucks. It's very hard work with long hours. If you get a few bad crop years in a row, you starve. If you become disabled, you starve. If you become seriously ill, far away from decent medical care, you die. Of course the community can help you, but you're surrounded by other homesteaders with the same problems.

That is, more or less, the way it was for most of human history. These days, we specialize. We assign a few people to produce food, a few people to educate the young, a few people to treat illness, and so on. In most of the Western world, we organize this with money. If I opt out of the system to become a homesteader and work the land for food for my family, that is my full-time job. I don't contribute anything extra to society, and so I have no (or little) money. My life becomes essentially that of a peasant. Oh, sure, I have vaccines and civil rights and maybe running water, so my life isn't as bad as that of a medieval peasant, but it's still fundamentally similar: I give up most of the advantages of living in a modern, industrialized society.
