2d. This right of ownership that springs from labor excludes the possibility of any other right of ownership. If a man be rightfully entitled to the produce of his labor, then no one can be rightfully entitled to the ownership of anything which is not the produce of his labor, or the labor of some one else from whom the right has passed to him. If production give to the producer the right to exclusive possession and enjoyment, there can rightfully be no exclusive possession and enjoyment of anything not the production of labor, and the recognition of private property in land is a wrong. For the right to the produce of labor cannot be enjoyed without the right to the free use of the opportunities offered by nature, and to admit the right of property in these is to deny the right of property in the produce of labor. When non-producers can claim as rent a portion of the wealth created by producers, the right of the producers to the fruits of their labor is to that extent denied. There is no escape from this position. To affirm that a man can rightfully claim exclusive ownership in his own labor when embodied in material things, is to deny that any one can rightfully claim exclusive ownership in land. To affirm the rightfulness of property in land, is to affirm a claim which has no warrant in nature, as against a claim founded in the organization of man and the laws of the material universe. What most prevents the realization of the injustice of private property in land is the habit of including all the things that are made the subject of ownership in one category, as property, or, if any distinction is made, drawing the line, according to the unphilosophical distinction of the lawyers, between personal property and real estate, or things movable and things immovable. The real and natural distinction is between things which are the produce of labor and things which are the gratuitous offerings of nature; or, to adopt the terms of political economy, between wealth and land. These two classes of things are in essence and relations widely different, and to class them together as property is to confuse all thought when we come to consider the justice or the injustice, the right or the wrong of property. A house and the lot on which it stands are alike property, as being the subject of ownership, and are alike classed by the lawyers as real estate. Yet in nature and relations they differ widely. The one is produced by human labor, and belongs to the class in political economy styled wealth. The other is a part of nature, and belongs to the class in political economy styled land.
