Perot can afford a small army to reclaim any land that is "lost" to squatters -- he is just saying its property that is hard to take to a place where his army can't reach .. and property that exists on electronic paper is rather easy to do that with . MF Global.
Barnhardt's credo is correct - if you can't stand over it an protect it, it isn't yours. Perot isn't really saying anything different - is just that he can hire a bunch of people to stand over it - Urban or Rural. He just isn't saying it out loud. . And really that is the lesson here. Your best STHF asset is people. When I saw your post I immediately thought - "my wife. " You can have all of the guns, ammo, food, water filtration etc, but without other people that stuff isn't going to end up serving you. It will serve those who had more people and took it from you. You can only fire so many bullets by yourself. The communities tat prosper will be the ones that figure out how to self police the fastest. Ideally that is a Sheriff who deputizes everyone with a firearm, and give them the "authoritah" to do what needs to be done to put down any ferals. If you still have someone protecting individual rights ( like the right to own property, or a gun etc) you have the safety and justice necessary to have a productive community and an economy.
The danger is that the Sheriff with his new found army then takes it upon himself to confiscate and redistribute supplies, rather than asking for donations. (or just goes full "the postman" on you.. But then that will be the basic rule that I mentioned before - anyone demanding something from you out of duty, or kindness, or charity is an enemy - even if they don't carry with them the implicit use of force. You give them a handout once than they will expect it again, and tell others you are hoarding if they don't get it.
Anyone asking upfront to work for what they will receive probably isn't going to tell anyone. They don't want competition for the job they got from you, and they understand that getting paid means they perform. They already understand that they aren't entitled to anything, and admit as much when they ask if there is anything they can do for you to earn their crust of bread. That doesn't mean they won't turn on you, it just makes it less likely they are the sort to do it, and more likely they are the sort to be grateful and happy for the opportunities you are able to provide to them.
