I don't know where this issue should go... might be moved to somewhere in 'Monies' thread ? or  maybe we need an 'Economics' thread in this forum?

Anyway, a book about Daniel Suelo, the man who doesn't use money, by Mark Lundeen
https://www.amazon.com/Man-Who-Quit-Money/dp/1594485690/ref=cm_rdp_product

and here's Suelo's website
https://sites.google.com/site/livingwithoutmoney/

(And, while I'm at it, for info on a perfectly feasible...historically verified!.. debt-free money system, see
ami.org)

Is it this book?

Yup ;)   I do have to warn that Suelo bases his moneylessness on his 'spiritual' and 'philosophical' experiences.

(And author Sundeen has a brand new one "The Unsettlers" that looks to be very, very interesting ;)
