Transitioning into collaborative ownership (which would benefit all people involved) it would be a non-violent means of doing so as people would voluntarily do this based on the benefits.
As long as it would be on a voluntary basis, I have no problem with communities trying this idea out. No doubt, in a free world, where all human interaction is voluntary, different groups of people will live different kinds of lives with different rules and practices. It is an empirical question which rules of ownership benefits people the most, and I support the practical experimentation with different rules.
However, my prediction is that even though collaborative ownership might work in small enough groups, it will break down when groups grow bigger.
