If people have no land they cannot survive

If we have no land of our own we cannot survive because we must eat and for that we need sunlight to fall onto the land which grows into crops and meat. If we are denied land then there is no possibility to survive. To deny land to others is similar to killing them directly. We cannot be self reliant if we have no land of our own. The Welfare State is perhaps justified if people are denied land. If people have no land they have no means to provide for themselves and so the landowners owe succour and protection to the poor.
