In a somewhat paradoxical fashion, it would be cheaper to buy and own many things over an extended period of time versus renting them. However, pooling resources to buy just one of something and have it be accessible to a community seems like the more ideal sustainable approach.. But we also see perversions of the 'sharing' model with things like ride-sharing and AirBnB. Just something some of the comments (i.e. on laundry and tools) made me think about.
