I think the conspiracy and the avoidance of confortation is what they are getting them for.
If you want to fight the authority of the FDA to regulate raw milk sales, you should have sold the actual cows from customer to customer then extract the milk for that customer and then transfer it to the next customer.
If the customer owns the cow, then we aren’t selling raw milk, we are selling raw cow...get it?
Your other choice is to sell the cow to someone willing to challenge their authority without any tie to the farm, this person milks the cow and sells the raw milk and does it publicly so the FDA can try to sue / stop him
I don’t think someone engaging in private commerce can be stopped, just like I don’t think a Amish person can be stopped by trading raw milk for chicken feed.
