Presumably because you need to eat. Farmers are in the area. My wife does accounting for the food producer they sell to. I photograph their weddings. My wife’s mom helps run the healthcare for the area. My friend sells them equipment.

People generally don’t live where it doesn’t make at least some economic sense, and those farmers would probably stop farming if they didn’t have at least some basic necessities and amenities nearby.

Accounting and heathcare management can trivially be done remotely.

But it might not really matter. Do small farms produce a noticeable amount of food in our food supply? I thought it all was giant farms with giant machinery, not family farms, that actually produced food.

(Edited to try to make it more clear that was a real question. Maybe family farms are important for the food supply?)

Family farms large are “giant farms” nowadays, at least in my area. Nobody is farming 50 acres, they all have hundreds or even thousands. You can only really be born in to it when farmland is $10,000 an acre and the equipment will run you hundreds of thousands of dollars more.

And they’re all stupidly wealthy for the amount of work they do, but that’s another matter.

Note: that’s all for crops. Raising animals seems to be another matter with plenty of smaller farms - and they do more work too.

While all large farms are family farms as well, the total number of such large farms is, what, 10,000 in the USA? By a bunch of very rich people? The exact people who don't need their lifestyle subsidized by people in urban areas to keep living in the country otherwise they'll move away and stop growing our food.
