deathandtaxes, what you are doing is ignoring the thread title. The security companies would have contracts only with those who could afford to pay them and their would be no independent courts. Your mistake is to assume that you can have no government and still have a system of justice.
Of course there would still be courts. Complaints between security company and victims would be handled by PRIVATE courts.
Private courts are not public and have an incentive to make money.
Corruption would be instant and anyone with the right amount of money could buy them.
Justice must always be independant and cannot be commercialized.
Anyone thinking this is at least plausable has got no idea of the sots of complex problems arise in a society and how humanity has gone through some pretty shitty time to come to the conclusion that this is the best way to get any kind of justice.
I mean, just for amusement, imagine that everyone could just start their own private courtroom.
What standards/law will your judges follow?
What if another firm opens and they don't agree with your interpretation of the law?
Who will then judge wether your court is right or the other court is right?
Where would your court find authority to actually execute the interpretation of these laws?
What if the other court doesn't agree and merges with a PMC?
Who's your daddy then, huh?
I mean, if they do it then you will also need to do so because you need to protect your interpretation of the law.
It is realy a very very bad idea to just let everything to the market.
The market doesn't care at the core and your money is not enough to make them care enough.
They do their best to make you think tho that your money can make a difference, but in fact, without a revolution you would be powerless against these gigants as they have ways to make you comply without you even knowing.
Yes, that's a 3 feet dildo right up your arse right there. Didn't even notice, right?
It's stupid because it would create corporations which are too powerfull and yet only motivated by becoming more powerfull, by whatever means. If they are forced to listen to the people because people stop buying their stuff then they will listen. If they can make a ton of moneys by poisoning the water supply from the freshly accuired water distribution firm and then sell you the cure they will do it.
There is very little a big corporation is not willing to do for money and power and without a separate, independent and overarching justice system and a force to execute these judgements there is virtually no hope of humanity developing any further.
