You could be right...but I encourage you to think that through very carefully. Even in most worst case scenarios of climate change killing most food production, it's a slow process, taking quite a few years. The people who might eventually come to take by force what someone has as a result of exceptional planning and execution could be the same people who have been politely asking for some extra food for years. And those hungry people have been thinking about it and talking to other hungry people about it for a good long time. Also: the local government and pseudo-government entities might insist on redistribution. And that redistribution might be entirely legal.
