Volunteerism would take currency out of the picture. Individuals would volunteer to provide the needs and wants of others in any way they can; be it advice, labor, materials, or I-pads. In exchange, others would volunteer to help the volunteer. I feel this process would self-assemble into a workable society. The old hippie communes had the right ideas, some still exist. Local meetings would help those involved identify the most important needs and wants and find those individuals who can fill the bill. Able non-participants would not survive very well. One need that will have to be addressed are the care of those who cannot contribute like the aged and ill. (A minority, in my opinion.)
