Free range poultry can be bought from farmers off the farm in many states as well. It depends on the state. Let me tell you, if you haven't ever had free range chicken, you're going to be shocked at how different and how much better it tastes.
There is even a way to buy milk straight from the farmer, although, this gets a bit tricky, and many farmers will not do it unless they know you. Farmers can sell milk for "animal purposes" (I forgot the term used), i.e., to feed to an orphaned calf, kid, etc. However, if the authorities find out what the real deal is, then there can be some consequences.
The only way the laws will be changed is when enough people threaten to vote the scum out of office unless the laws are changed. I don't foresee a change though, as the consumer is happy with the way things are now. This is what they have grown up on. They don't know how much more delicious an non-commercial chicken or egg is. They are unfamiliar with grass-fed beef.
There is a "homeland security" arguement against a consolotated food industry. There are actually very few corporate processing facilities. This is because they are so huge. Animals are transported from all areas of the U.S. to these facilities.
Just think of the damage a terrorist could do working in a processing facility. He/she could poison Americans all across the country. Worse yet, if a terrorist destroyed these key processing facilities, it would cause devastation within the U.S.
Who cares though right? As long as the politicians stay in office.
