So you want to force your rules on others?Thats pretty much what we have already.Minimise the problems by reducing the restrictions on what people can and cant do?
News at 11, some people are twats (take the two guys in the OP), in your world we would couldn't do anything until they harmed someone.
Its why there is preventative legislation, its to try and prevent crime, in your world no one can be stopped from doing something until they have harmed someone.
You have a very narrow insulated view of the world that makes it near impossible to comprehend. First, I say that people would be free to do what they like, and you respond with, you want to enforce your rules on others. I seriously have to question someone who sees offering one freedom as forcing a rule upon them. This is some of the most bizarre logic you have offered up so far.
And to suggest we already have a co-operative system and people not rebelling against this is absurd. The current system we have is based on heirachy and competition. The majority of the people don't benefit from the system (it is elitist, benefiting a tiny minority at the expense of the majority), billions of people barely scrape a living, and because of these overt displays of injustice, inequality and fairness, so called criminal behaviour is manifested, all the way up the scale to full blown war. I am unsure what world you are living in, but it is hardly co-operative, and it certainly doesn't minimise terrorism or war. You obviously view the world through your rose colored glasses and your first world prison of comfort and ease.
And what are you talking about minimising what people can and can't do. the very opposite is true. What an anarchist system does is reduce the motivation to do dumb shit, so people can still do all the dumb shit they have ever done, but under such a system they will not be rewarded for it, and therefore less likely to indulge in such behaviour.
And legislature isn't preventative. You simply can't prevent people doing dumb shit. Legislature is a deterrent and a punitive mechanism. That's it, if it could prevent crime there would already be no such thing. The goal is to reduce the reasons why people do dumb shit in the first place. Remove any incentive to act anti social, by changing the system to a fairer less punitive model, based on community and co-operation, this alone will minimise the desire for those to go against it.
