If every individual unites into a community working together for the common good, there will not be a cry of hunger. a centrally controlled system will have no effect if all the individuals working together will become strong communal.
That would be really beautiful.
But let's be honest, with what is happening right now, I don't think all of the people would be accepting that way. Usually, if a family could just live by themselves, they won't bother helping others because the most important for them is to save themselves. If other poeple are struggling to get some food, it is not their problem.
Many people do not care that they will be independent in their own way or with their own families, so individual communities rarely occur because division must have hunger for sure if they cannot unite, but still if they believe in a matter of conviction then maybe they can still survive and will continue to seek without affecting centrally with the community.
