I ask you again, Please explain how one person's need constitutes a just claim on the property of another.
In a society, each member has a just claim on property of their compatriots - it is a codified and well recognized feature of a society. Governments formalize and enforce these claims all the time. We are interdependent. A baby has a just claim on its parents, and on other members of society should its biological parents falter. An injured or distressed person has a just claim on the good efforts of his able bodied neighbors. A passerby claims your polite dealings. You make a claim on society for protection, justice, and right to seek happiness. That's what makes a society: claim and counterclaim, justly honored by its decent members.
