Why do you believe in it, do you approve it in theory or also in practice? I think a lot of people approve of anarchism in theory but rejects the possibility of it to be put in practice unless we live in an utopia.. which I don't think we do, unfortunately. Maybe techno-anarchism would be more practical? Technology is such badly regulated and ordinary people are punished harsher than corporate so I really think techno-anarchism deserves a lot more attention (not saying anarchism itself doesn't) I see a lot of people here are more knowledgeable than me so don't take my word so seriously, maybe I shouldn't be expressing my idiot thoughts on it, or maybe just embrace it and ask regardless of any shame I might get.
I'm not trying to be mean to anyone, just genuinely wanted to discuss with whoever is willing to chip in on the topic.
My thoughts about power balance, power vacuum and so on are simple.
Those who'd want to take power are usually cowards. It's no good to dead. It's no good if there's nothing remaining to have power over. The one who can destroy a thing owns it.
There's the Cold War MAD doctrine which was employed by all sides and simultaneously vilified by green, pacifist etc parties. But maybe now we can see how the world without MAD looks and see that it's better when everyone is armed to their teeth.
You can come to the truth from anywhere if you seek it honestly. It's the same with weapons - everyone arming themselves and being ready to defend themselves create a group immunity, where sociopathic behaviors get rewarded less, and sociopaths are more challenged in accumulating power. Again, the only real kind of ownership is where you can destroy your property. You own your life when you are capable of sacrificing it as you wish. When a society is armed to its teeth, then its power imposed upon any kind of power-accumulating authorities is more than theirs, and when it's disarmed, it's nothing compared to theirs.
People being accustomed to anarchy and actively wanting it are not enough. People want to try all kinds of things. People fear. People are malicious. People want worse societies when they believe they will be the ones imposing injustice upon others. People are also just stupid.
The Internet is not an example of anarchy, of course. It's nothing without its backbone cables built with participation of governments and enormous corporations and treated as strategic assets. It's no more anarchist than sea ports. There was a sprinkle of anarchy there in its transient years from an elitarian scientific thing to a common medium. That was not stable. Nothing anarchist can be stable in a system of dominating hierarchy.
I admit it was easy to buy into this fairy tale when I was a kid. In 2006 it seemed that the humanity is one step from becoming free and, well, humane.
All that said, I think eventually we win.
But we can never know, because our perception is always poisoned. It's much easier to do that than to thoroughly weed us out (it has a better characteristic considering their superior power, while the latter is not plausible to do). That's what the adversary is always doing. Any "smart and considered" action is likely wrong, because it's based on compromised perception. This is just like scammers calling you to "help catch criminals" or something.
The only way anarchism ever succeeds is by acting on rigid principle, as if fighting blindfolded.
