Such towns are easy to spot. All you need to do is head down any county road. When you spot the community with the junk cars scattered about like we see on the 'American Pickers" show, used tires for sale, callasping tool sheds, outside dog houses with dogs on a chain, barbwire fences, cars parked on front yard, gravel driveways, every post is decorated with "No Tresspassing" signs, and a burn pile in the back yard....you have found your town! Most residents will be unfamiliar with 'Laissez-faire' but will be advocates of 'Leave me alone!" And isn't that what you are looking for, a place where folks are not into each others business?
Now, you are aware, your second, inevitable question will be invalid. That question is, "Is this a safe neightborhood?" The answer to that question is directly related to populaton density. How far do you want to drive?
Why not just pick a town where you want to live and buy a condo or town home. They do all that nanny state bothersome stuff like mowing, exterior painting etc.
Oh wait, then there'd be HOA rules you'd have to follow and they're worse than the government.
I agree with Marc... no where
