In today's modern society the law often in conjunction with the government is constantly encroaching upon man's natural right to enjoy and to control the very things that he owns. In a country without private property, whether that property is owned by the government outright, or by the people in common, the individual, has no safe sanctuary, since the very steps that he takes upon any part of the earth, is not his own.
While it might sound enticing, fair, or even Christian, for everyone to own everything in common, the actuality of it all is far from some sort of earthly paradise. First, no matter how the bread is sliced, somebody is going to have effectively more rights than you to common land, and further, that somebody will often have less responsibility to work on that same land as you do. In point of fact, that is one of the fundamental lies of communism, to which those in power, those with arms, those that are connected, decide just how much or how little freedom of action, or freedom of conscience, that a given citizen may have, and through it all it will be made abundantly clear that not all commoners are equal, and those that are less equal will have to make do with whatever the State elects to parcel out to them.
It doesn't take a genius to understand intuitively as well as in action that you do not treat your own private property the same way that you treat property that you do not own or property in common, or property controlled by some State agency. In truth, you treat your own property with far more concern and care than any other property, basically because you have "skin in the game" knowing that how your treat your property has a direct material effect upon you, whereas property held in common, or anonymously, is not property that overly concerns you one way or another, so, for instance, if you have trash you toss it, cause you don't really care, even though you should.
Another very important aspect of private property, is that this is your line of defense from State encroachment upon you as a person, so that without private property, without private property rights, there is no safe haven, because a government that does not respect private property, will not typically respect you as a person, and rather than seeing you a person with certain inalienable rights, will see you instead as someone created to serve the State and if necessary, will make sure that you are obedient to this dictate.
When it comes to private property, the interest of the State should be strictly related to the fairness of as well as the acquisition of the holding of private property for individuals and not in contrast for the State to aggrandize unto themselves or to take unfairly private property from individuals. A country with strong individual private property rights is a country made up of sovereign individuals that collectively may then decide to band together so as to protect those rights, and thereby become a country of the people, by the people, and for the people.
