'Owning'things creates scarcity.If more objects were shared, the way we share books from libraries....

During the Spanish Revolution of 1936-1938, in the anarchist zones, everyone had to share- even automobiles. The rule was that whenever you parked your car, you had to leave the keys in the ignition, so any needy passerby could use 'your' car if they wanted. The anarchist collectives controlled Barcelona and several millions took part in the experiment. It worked- the end came because of military defeat at the hands of Franco, and not due to any economic 'flaw.'
