The future of the world...

I would suggest you can never 100% trust anyone outside your own nearest and dearest but I would not allow that to exclude the option of seeking out a community-based solution to the problem. I would further suggest you don't actually NEED to trust everyone implicitly anyway; as long as everyone or at least, the majority, within a small community setup is attuned to the idea of getting by for long periods without outside help, then that's a reasonably firm basis to build on.
