A hunter-gatherer dropped into a metropolis where all the logistics has suddenly failed would be as dead as everybody else.
I didn’t suggest that it could, but the number that it can support is certainly more than zero. If that’s the only choice in a hypothetical scenario where global infrastructure goes kablooey, then people who can figure out how to provide for themselves will outlive those who can’t. From there it’s natural selection.
You're statistically likely to simply be stuck in collapsing logistics system alongside everyone else: whether you can kill and dress your own rabbit doesn't matter because their aren't any.
But then there's rabbit starvation... https://web.archive.org/web/20090405155151/https://www.westo...
