Hmmmm . . . I seem to remember reading somewhere about this fellow called Jesus who exhorted people to sell all of their possessions and give the money to the poor if they truly wished to follow Him.   He also said something to the effect that if a person has two coats, he/she should give one to someone else who has none.  This Jesus guy also led a rather nomadic life, moving from place to place with His friends, all of them subsisting on communally shared resources.  Indeed, Jesus life of ministry with His disciples is an excellent example of truly living in community, or to put it another way, of communism.  He was an interesting fellow, this Jesus.  You should read about Him.
