Why Private Property Rights Matter

If though most readers knows what private property is I’ll explain it anyway for those who don’t. Private property is the clothes you own, the car you own, the house you own, etc. Basically anything that you own is private property including money. The key word here is private. Otherwise the state owns the property and can do what it wants with the property.
Since you own the property you can give it away, loan it out, or even destroy it if you wish. It is yours to do whatever you want with it.  But nobody can take it without your permission. “Thou shall not steal.” as it says in The Ten Commandments. God put that commandment in there for a reason. Owning private property is natural for mankind. It is part of our nature. It is even part of the Buddha’s Five Precepts. In a communal society stealing is not even a concept. How can you steal X from someone when everyone in the society owns X? By that very definition if you own X too then you are not stealing.
You could still get in trouble if you take something from somebody without the state’s permission. Since the state really owns the property it decides who gets what.  You might be taking something that was intended for someone else determined by the state. Or you could take something that was private property of the state and only the state. You really think private property will be  completely abolished in a communal society? The powers-that-be will always own their private property. That’s the way it was in the Soviet Union.
Also, if two or more people want the same object then someone has to determine who gets the object. Who you think that will be? Someone in authority of course like the state. If we are talking about large numbers of people like 10 or more people then the state has to determine who will get the object.  Smaller groups of people could get away with a pure communal society but even that could be problematic unless they are family or close friends.  By the way, if the state wants that object too then guess who gets it. The state of course. It will always get the best of everything.
Here are other things to think about in a communal society: The state could take something from you and give it to someone you don’t like or you don’t think needs it or deserves it. This could happen if the receiver is a friend or relative of the state. Also, if you spend time, effort, and/or money in making a product and then the state takes it from you and gives it to someone else where is the incentive to make it again just to have the state take it away from you again? None, unless you are making it for yourself and doing it for fun.
