There is always distrust and something to die for. Let's take your friends and family? What if someone kills your partner either just for fun (which does happen) or because of a differing morale. What now? Can you still trust people for this not happening again?
Don't get me wrong, I am also hoping for a better, freeer and more trustworthy world. More peace and such but you cannot expect this just from simplification.
