I find the idea of human nature unsettlingly constrictive though. We shouldn't always be constrained by what's 'natural': it's important to recognise what's positive and negative about our nature and make decisions which we think will improve ourselves.
It's no accident that many of the earliest anarchists were biologists (Kropotkin being an oft-used example): there are elements of the animal world that seem to contradict the traditional view of the animal world. I feel like the idea of humans as savage and individualistic in nature is an idea that's been propagated by those who have a vested interest in keeping us scared of ourselves and each other.
I respect your view and in my more cynical moments I've often thought similar things, and I'm by no means perfect, but I believe that systems of organisation such as syndicalism or just little things like forming communities that are kind and caring, could potentially abort the development of a conventional 'free-market' in a well-organised, stateless society.
Getting kind of academic though >_>
ANYWAY
CHIPTUNEZ HUH?
