Nothing has changed since prehistoric times, in that the ultimate back-up of ownership is the threat of violence from other beings, human or otherwise. There’s no “natural ownership” based on a person’s demonstrated or potential sense of responsibility.
Although Blake’s son is lucky that she is a responsible mom, other parents are not so responsible. Children are not “given” to their parents as a symbol of their good favor in the eyes of the god(s) for being responsible (this does occur sometimes in the case of adoption). However, expressing love in terms of responsibility (I love, therefore I…[insert your favorite self-congratulatory responsible act or habit here]) is a valid, though insufficient, thing to do.
Similarly, ownership of land or other things is not always a reward of responsibility. Inheritance is an example that proves that; inheritance is an action of law that is blind to responsibility.
Modern land/house ownership, in most practical cases, is merely advanced renting. In most cases, the bank owns the property and the so-called owner pays the bank periodically with the threat of losing (ahem) ownership if payments don’t come in on time. Like Bruce said, there are many local, state, and even federal laws that “determine” the act of “ownership” such that a home owner can be seen as one who, by virtue of long practice, and elaborate self-deception, has learned to dance a complex sacrificial dance, where the offering is one’s life to the state. Why else would a “natural” man (or woman), supposedly loving freedom, find him or herself in such a prison of time and chores and expectations? By observing natural animals, one can easily surmise that true natural man, no closer to violence and primitive behavior than we are, suffered due to nature, it is true, but also had plenty of time for lazing in the sun, mating, and playing with the cubs. He would laugh out loud at the notion that, should he stake his claim with a shout to the gods, or by giving an antelope haunch to the hairy guy two valleys down, that his camp would be his from then on, into perpetuity, without the need for defending it, should he want to.
I saw the water extraction rights thing first hand in Owens Valley, California, when I was flown out with an illness to hospital from the southern Sierra. Owens Valley is a bare wasteland where once orange groves flourished. Guess where the water goes? Many miles away, through the mountains and desert no less, to Los Angeles, where a month earlier I sat, nursing an over-used knee, in front of an elaborate, computer-controlled, water jet fountain. Do you think the Owens Valley farmers objected to the takeover? At gunpoint, yes, they did.
Similarly, in New London, CT, where I have lived and worked, the city took land owners’ homes and property (sometimes through long and protracted legal battles - the owners did not want to sell), essentially to offer the area for use by a private corporation - Pfizer. Not only did the owners lose their homes, but also (since at least one also owned rental property) future profit from the use or sale of that land after it had gained value.
