Comment by antisthenes

There are a lot more of regular reasonable folks who own guns (approximately 134 million in USA) than those who have some kind of meme warlord fantasy.

Which is to say, normal people really don't like shooting each other, and they REALLY don't like being shot at, so most normal folks would eliminate the threat of crazy warlords first, then form some kind of organized militia group to repel small groups of raiders/thieves.

Any large group of raiders would very quickly fall victim to its own internal politics and lack of resources, because they don't produce anything. You can't have a group that's 100% raiders.

It's just not going to look like Mad Max, ever. Sorry to disappoint.
