If I recall correctly, native American societies were somewhat the same way. If someone needed or wanted something a tribe-mate had, or another tribe had for that matter, they just took it. Not much of a private property ethic in those days, more of a share and share alike mentality with frequent potlatches. In the absence of government assistance programs, the impulse to share with one's neighbors is admirable; unfortunately, it has devolved into the entitlement mentality not only towards government largesse, but also toward other people's property. Certainly not compatible with concepts of private property, as you point out.
Someone here on the 'Fire not many months ago familiar with Native America culture had a different take on it. He wrote that in whatever Native America tribe he was familiar with, that anything was fair game, and if you weren't strong enough to protect your property or your woman, then F you, you are a pussy and deserved to get taken advantage of because you were weak. The strong took whatever they wanted. That is how tribal heirarchy ws established.
The Scandinavian culture has a stronger share and share alike tradition from what I've read, which goes with the traditional social liberalism that has been a stable in the upper midwest.
