wp:Property is theft (rd to Pierre-Joseph Proudhon#Private property and the state)

Property, in his view, is both theft and freedom. It is theft when one person owns the property that others need to survive. Property is theft when the person who owns it can own it without occupying it and can derive rent, income, and profit simply because they hold legal title

So if a person builds a house, and then rents it, that person is a thief, but if wt:thon sells it, that might be okay? Maybe don't build houses you don't intend to live in or give away, I suppose.
