"A person in our society cannot sleep without paying for the place where he sleeps; he has the right to have free air or water or sunlight only when he is on the road. The only right he has is to walk along this road; until he becomes tired, or he cannot walk, he has to continue walking. The bodies of men and women, and even more importantly, their children, should not be bought and sold. So too the water, the land and air, because these things are necessary conditions of this existence."
