I am having difficulties to fit the term "socialism" into this context. When you speak of a world without borders, then to my mind, it's not about socialism but it's a form of positive anarchy. An anarchical way of living is something which does not need laws and their enforcement, for the rules are already clear to all those living and working together. My definition of "anarchy" will probably differentiate from your definition of anarchy. That's why I placed the attribute "positive" in front of it. Are you interested in further readings? I am not sure, if I already recommended Darren Allan to you and his book "33 Myths"?
Well, the anarchy that is my ideal is called "communism" which is a stateless, classless and moneyless society. You know, like the tribes of old. And my definition of anarchy can't work in a capitalist system as capitalism enforces class-division. Anarchy does not mean that there are no leaders and followers, by the way, but it does mean that there are no rulers and ruled.
Thanks for the book recommendation :-) I'll look into it if I find the time...
You are welcome.
It's worth reading. :)
