The reason it's different is because it replaces the other 2 methods serving capital with the 1 option that serves the community. It's more like a store where you don't buy anything, but then give those items to the community when you no longer need them. Buy? Rent? Why do those things when you could borrow from the community, help improve it, and then return it to the community? Having a picnic next to the lake? Borrow a cooler for a day! Need to drive across the country? Borrow an electric car for a year! Need something at all times, like a cellphone or a washing machine? Borrow it indefinitely!

Instead of overproducing items at the expense of killing us all in climate crisis, a library economy produces what's necessary and lets the people decide what's best for the items through direct democracy and electing library stewards to handle the operation of the library. Nothing is commoditized, nothing prevents you from owning things, and nothing prevents you from building your own things. It incentivizes highly durable, repairable items. It creates the foundation for mutualism and helping each other. Most importantly to me, it creates a society where we no longer have to consider money while also enriching our lives.
