Sounds like a recipe for some exploitive con artist to come in and take advantage of their naivete. Sounds nice but so do most utopias. Human nature, however, tends against utopian ideals.
I think if this is about living in community, though, then one could see it as a call to share and treat things in a more communal way.
Just like turning the other cheek would be fine for conflict resolution within a community but does not work so well when facing down the cold hard world. There's a time and a place to do that, but there's also a time and a place to take self-defence classes and use that knowledge.
