A lot of people buy flour, rice, and oats (the cheap and hard to grow yourself grains) and grow the fancy stuff (nice fruits and veg, maybe inoculated mushroom logs) and maybe have some meat roaming in tractors like chickens, themselves. For that use case 0.5-1 acre can cover a person’s food needs easy if doing a smart permaculture type style. (Obviously monocultures take way more space per calorie).
I would recommend looking into aquaponics as well if space is a constraint.
But both take years to set up, and a good amount of labour. It isn’t just like having your vegetable garden you water on weekends.
Also, if in an arid region, the acerage requirements go up.
They exist in the world. They are not very popular, judging by the fact that you’ve not heard of them.
You need much more than 1 acre per person. First Google result is 5-6 per person.
