I don't get the small businesses fetishism. Large companies are efficient, resilient, more likely to follow the letter of the law, and more scalably prosecutable if they don't.

Small farms are inefficient though. Farming needs a diverse range of skilled labor but infrequently: the industry as a whole trends towards larger land holders being serviced by specialist labor forces which work seasonally or regionally.

And then within that bucket, it's fairly obvious that larger holders are going to be much more resilient to regional problems if they have diversified land holdings where one area can support a downturn in another.

This is all Renaissance era knowledge.

If that's your answer then you're vastly underestimating how much farmland there is. We have 1.6 million small farms, averaging a couple hundred acres. Large farms usually have a couple thousand acres.

If every farm in the US was around 3000 acres, we would still have a quarter million farms. Even 100k acre mega farms would leave us with 8000+ farms.
