There is only one way to understand the initiation of ownership and private property. Their are conditions
That which is homesteaded must be, just prior, unowned.
Nothing which is already owned may be homesteaded.
That which is homesteaded must be put to use. This is meant to prevent ownership be declaration. “I hereby own all unowned space”. No.

Oh, wait! I forgot the other option! This one is most popular right now with my students. Everyone plays really nice and to each what satisfies his needs and from each what he can produce. Everyone plays nice. Sharing. Hugs. Smiles. Hold on. We tried this before? Look back at the death toll of Communism in the 20th c. to see what that was really like.
