your typical business isn't working at the same level of the maslov pyramid than a farm. I don't want a world where only the wealthy can afford to give milk to their kids
I think because farms need to be a certain size to be effective.
And, even though they might be worth a lot as real-estate, the land could be worth millions, the people farming could be poor.
Guess, to your point. If a family owns a dry cleaner, similar situation.
