Religion

Without context.

The rest of the context is that it was entirely voluntarily, and there was no judgment and no penalty for not contributing. As soon as it was perceived to be a status symbol or somehow required, people starting lying about their "taxes" and idea it was required was corrected. Try that with any non-utopian socialist plan. First thing is government dictates, second thing is government enforcement with violence against those who don't agree with strong judgments from the (self-)righteous, most of whom believe it's better for others to give so that the believers may receive (either stuff or power).

Voluntarily socialism has a lot of traditional names. Then again, that means it's not really socialism, so there's a bit of definition-shifting and fallacious assumption-making in that sentence.

The rest of the context is that they were there waiting for Jesus' return. What need had they of possessions? They were sojourners, and awaiting their true government--not the Roman-imposed occupation government that abused the population and which Jesus had nothing much to say about. The children of those who committed self-impoverishment probably weren't too happy at going from the top 20% to the bottom 5%. Nor their wives or servants.
