Freedom and fast food

In Super Size Me, the concept of externality is very clear. Everything has a hidden cost associated with it. I remember reading a report written by some vegan groups that every meat hamburger should be sold around $100 because to feed those animals it requires a lot of water, need land to farm corps to feed those animals, and therefor there is pollution. Another example would be if a company skip the processed of processing the wastes, their product will be cheaper and more competitive. If some company just dig out minerals without the obligation of taking care of the environment, they sure will be more competitive in the market. Total free market for cause is chaotic, only mafias and drug dealers will own everything. There is a cost to these business so the government, supposedly the collection of people's opinion, will stop it. Even in our body there are white cells to eat up those cancer cells. I have always thought that a sate of lawless free mind is a corrupted, and animal-like mind. Humanity, implies disciplines, control, and logic.
