- Move to a region that is self-sustaining and is little impacted by global warming.

Honest question: in the event of some kind of widespread collapse of civilization, there will be hundreds of millions of starving people. For the purpose of this question, I don't think it matters much whether its a 'fast' or 'slow' collapse.
Assuming you have some kind of self sufficient farm and a bunch of guns and other defenses, does it seem likely that you can keep what food you have and what food you can produce in the future from a large number of starving people?
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.
