Or you can take natural law thinkers like Grotius - in essence, their thinking derived from religion thus: you are owned by God -> you cannot kill yourself -> in times of hardship (an in extremis condition) you must take what you need in order to live. Very interesting, as he also defined property in terms of his religious beliefs...

I guess what I'm getting at is either you have the people breaking into the grain stores (in Grotius' day, anyway) or you provide some means of subsistence.
