There are no property rights than can be revoked by absentee owners. That is, there are no remote lenders or landlords that can throw you out when they choose. This might be a scary thought for those who would wish to hoard resources and profit from others' need for them. But notice that the principle works several ways. Not only is it meaningless to hoard unused resources for a rainy day, nobody else will have been allowed to do so either, so the resources won't particularly turn up missing when you might need them.
Ownership is based on effort and valuable contribution.
That is, if you are doing something meaningful, you might command a bigger chunk of real estate while doing so. This puts a pervasive emphasis on cooperation and good will. You don't just blindly move into one cubicle of a living complex in isolation from everybody else there. If there is already available living space there, the existing community of people there would be interested in what you can contribute. You would acquire the services and cooperation of your neighbors by demonstrating that your interaction is mutually beneficial.
