There's some scary stuff in the farming regulation. There was a law in the works called NAIS (national animal ID system)that severely intrudes on people's right to raise their own livestock. It was stirring up a storm of controversy in homesteaders' circles a decade ago, though I don't know the current state of that is.
While, the court process and decisions occurred during WW2, the law and the acts which, under it, created the controversy occurred before US involvement in WW2, it was more about the Great Depression/New Deal than the War.
I will go back and reread it to see whether that impression is correct or whether I've imputed my own bias to the court's decision since I read it, but given that I'm generally of a more statist bent than most people here I don't think it's just personal bias.
