Who can opt out, the person who is guilty? I don't see how anyone could opt out of the law.
Yes, anyone--even the guilty. But if the guilty opts out of a dispute, he or she must accept that their dispute is ongoing, and thereby risk the consequence of an on-going dispute.
I recognize the private armies would be selling their services if they were being funded, but my question is who is responsible for funding the armies that guard the entire society.
The armies themselves like any private organization is responsible for its own funding. If they require outside funding, they can seek investors or request donation.
Would the funding be a collective effort, and would the effort be equal or based on a person's income?
All terms of agreement to be hashed out by the involved parties.
I don't understand what you mean by the free market. Is that the majority?
Not necessarily. Consumer-based preferences will dictate "law" and one can opt-in or opt-out.
Perhaps private mediation is effective, but what would happen in the event that neither party is willing to accept an arrangement from the other?
Then they have an ongoing dispute.
What would be the overarching structure that both would be required to follow in the event neither are willing to accept an arrangement and who would determine this?
You are making statements which imply a government. The whole point is for the individuals to come to a resolution themselves. They accept the resolution because it's a subsequent product of the terms to which they've agreed. If they, or one party by some chance disagrees with the resolution, the parties involved can seek a different mediator, resolve their dispute by other means, or continue their dispute.
What happens if an individual has been tricked into making an agreement that was obviously unfair, but they did agree to it?
Then he or she has been tricked. This creates a different dispute for which the offended party can seek private mediation.
What happens if an individual has entered into life-long indentured servitude over the inability to pay back $100?
Slave contracts will not upheld in anarchy.
Would there be anyone to oversee which agreements or transactions are considered fair, or if there cannot be a resolution found between the parties?
If there is a need for such oversight then yes.
Uniformity is how well you are unified, if you're not cooperating in uniformity then I don't see how a society would be well structured.
That is not an argument; that is your impression. Two individuals are capable of cooperating--even if they don't completely share a sense of "uniformity." They need only be unified in their sense of individuality, and the sovereignty it affords.
Would these private militaries be educated in the art of war and what is Considered ethical in the global warfare community?
They will do whatever they can to sell their services successfully. If that necessitates being educated in art of war--as I presume it would--then that is what they'll do. If they're terrible at their jobs, then they obviously will find little success in selling their services, and lose favor to their competitors.
In a society where the individual is more important than the nation, the problem is that the individual has nothing to live for after death.
Please explain.
In the end, it is a trade-off: more freedom means less meaning, and more meaning means less freedom. You buy one by selling the other.
Meaning is subject to individual evaluation.
My point is that governments that are uniformed and meaning driven are more powerful than societies that lack uniformity and meaning.
You haven't substantiated that anaracho-capitalist society lacks "meaning." And I've stated before the only unity "required" is in the concept that they're all sovereign individuals.
There is a middle ground between the concepts of freedom and meaning. I am not supporting Nazism, but I am also not supporting anarchism. I believe that both have important aspects of a society that are important, but the ideal society is between them, which is the balance between freedom and power.
On the "middle ground" is where you find inconsistency. You'll discover once you've extended these "balanced" premises to their logical conclusions, they're absurd. If one maintains that individual autonomy is the highest good, then anarchy is the logical extension politically. There's no "balance." You either subscribe to individual autonomy or you subscribe to individual behavior being subject to someone else's arbitration.
I still don't understand what you mean by free market.
Education as well as certification can be sold. Private organizations supplying these goods can compete in an an open market.
It only is non-sequitur if you just read the bold letters. By summarizing information into key points, one often loses resolution and clarity, along with accuracy of the original text.
I emboldened those parts to demonstrate contradiction. You state they (members of an anarcho-capitalist society) can coordinate and then conclude that they lack organization because you allege they can't cooperate. So, let me ask you this: is voluntary organization impossible?
If the involved parties want one, then there could be.
and would the jury be paid by the community?
Not necessarily. Naturally, this would be paid for by the involved parties, or the parties in dispute. If however a group of individuals seek to streamline costs and pool their resources, they would be more than welcome to do so.
Who would determine the penalty for the crime?
The free market.
