It's not easy to run an animals or crops farm. It requires a lot of spare time, effort and care from the farmer. You need to work all day long to earn too little in return, because it's not only about planting the seeds, watering them or feeding the chickens once in a day. You need to check everyday (probably more than once) the crops to see if there are any diseases or parasites attacking it, you need to clean the chickens' spots, water and food trough, because it becomes dirty really fast, you need a very strict routine to not miss any daily task.
Some simply don't get it.
Let's take cows, for example, they don't care about anything, they don't care about summer or wintertime, they don't care about the rain outside, they won't give a damn yesterday was your birthday, they don't care it's Xmas, easter, your wedding, as soon as the sun starts to rise they will start a tantrum in the shed nobody will be able to sleep around. It's training, it's cold, you're sick, no, you have to go and bring them fresh water and straws, you can't imagine the noise if you ignore piglets or you're going to have the shock of your life seeing your chickens with half of their feathers left if you left them caged in.
I wouldn't want to go back to living on a farm even with the current technology, we have automated gates and feeders I can control from the house, but those mean money, a ton of money.
It looks romanticized, but in fact it's a harsh life or better saying, a survival experiment.
And, the shit! The tons of tons of animal shit you have to clean, every day from the floor, from the alls, even from their feeding through, tons of it in all color and density. How would this look in real life, famine, famine after famine as we go back closer to a hunter-gather civilization!
If this shit would have worked we wouldn't have famine in the poorest countries of the world where everyone lives on agriculture, but surprise, it doesn't work like that.
People may have to abandon cities to migrate to more rural areas where self sufficiency is a more achievable goal.
Then why in every famine known to men people are fleeing to the cities and not the other way around? It's still the same even now
