There's no such thing as free speech or the right to defend yourself in an anarchy - only power. If you want no government whatsoever you want tyranny.
No rulers does not mean no rules. If we stop obeying the mafia, the mafia will disappear. However, if you are so obsessed with being ruled, you can also be governed voluntarily
Hahah nooo, if you stop obeying the mafia - they KILL you.
Not if you defend yourself and help your neighbor, if he is attacked by mafia instead of helping the mafia if he becomes its target
How many neighbors is too many neighbors to organize this defense with? What you're describing sounds a whole lot like a government and police.
