If you rent out your phone then you have a phone-rental business, and since there is no private property that phone-rental business isn't owned by shareholders, it's owned by the workers in common.

If you are the only person working at your phone-rental business then you get to own and control the business and the business's stock of rental-phones, but if you have co-workers you'll have to share ownership and control of the phone-rental business and it's inventory with them.
