This is something I've tried to explain to the "get my arsenal and head for the mountains" types. There's strength in organization.
Some states have laws or regulations on what constitutes a village, town, city, etc., all graded by size, and each is authorized by what's usually called a "charter." Arkansas has no formal system - get some neighbors together, put up a sign, and you're Gunco Town.
In a SHTF situation this gives you a *serious* edge when dealing with FEMA or other feral governmental bodies, because you just moved from citizens|serfs to government|us. Here in Arkansas, Gunco Town would have all the same legal privileges and powers as, say, Little Rock.
Let me belabor the point:
One of you is the legally elected mayor.
Others are the legally elected city council.
Someone else is the chief of police.
Others are police officers.
Someone gets to be judge - it's elected all the way down to "village" level here.
Others can be firemen.
You're not a bunch of crazed survivalists to be herded off to the camps; now you're OFFICIAL, even if some of the paperwork might be dangling due to whatever caused the SHTF. Being official, you can demand assistance from the county and state. You can legally arrest, fine, detain, or imprison troublemakers. And you can levy your own taxes, without having to apply for permission from any county or state agencies.
Work it right, and each and very one of you is either an elected politician, city official, or carries a badge.
In other states you might be much more limited in what you could do, but that's no reason not to hit your local state.gov site and start investigating. And no reason you can't have your elections and portion out the jobs now, before an emergency.
