State is not that necessary in the modern world. It was usefull, but no more. I will not pay my taxes for shit...
Are you that confused? State is the collective. Without government, we'd have smog in the air, dirty water, pay-to-use parks, child labor, slavery, unsafe food.. Oh, and private armies constantly at war with each other.
Not to mention the fact that laws would be up to vigilante justice. In other words, I could come shoot you if your music was loud, rape your wife, etc... But, I suppose the rule of law and due process aren't important, just let everyone start killing each other like in the dark ages.
Good idea!
I am quite sure you just described civilization today... smog (perpetration of the petro-dollar), dirty water (fluoride anyone?), pay to use parks (National parks shut down because of sequestration?) child labor (although not directly but the public education removes 33% of a child's time from his family, and indoctrinates them into good institutionalized workers?) slavery (a portion of your labor is taken without your consent via wage taxes?) unsafe food (see Monsanto GMO?) and the private wars? how about the US military used to make damn sure the FRN stays the worlds 'reserve currency' aka the petro-dollar?
EDIT: ...And, you are absolutely free to shoot anyone for any reason... even now, the 'law' can only REACT to the action once taken.
