Mises was never keen to speak in terms of ethics, but the following excerpt from Socialism does a brilliant job dispatching the notion that ownership of property must necessarily preclude others from the benefits derived,
To have production goods in the economic sense, i.e. to make them serve one’s own economic purposes, it is not necessary to have them physically in the way that one must have consumption goods if one is to use them up or to use them lastingly. To drink coffee I do not need to own a coffee plantation in Brazil, an ocean steamer, and a coffee roasting plant, though all these means of production must be used to bring a cup of coffee to my table. Sufficient that others own these means of production and employ them for me. In the society which divides labor no one is exclusive owner of the means of production, either of the material things or of the personal element, capacity to work. All means of production render services to everyone who buys or sells on the market. Hence if we are disinclined here to speak of ownership as shared between consumers and owners of the means of production, we should have to regard consumers as the true owners in the natural sense and describe those who are considered as the owners in the legal sense as administrators of other people’s property.
