Whoa there. People, especially children, die every day because they can't afford food, clean water, or vital medical care [1]. So, are all of those suddenly communal property in your world? Who gets to decide how much of each of those resources each person deserves? Saying a commodity is "invalid" just because children are dying from not having it quickly leads to absurd situations like making organs communal property. What should be communal vs privately owned is contested every day at every level of government--this is a complex issue with no simple standards that can be universally applied.
