RE: War, taxation, and ultimately government itself will eventually go the same way as slavery and human sacrifice
Also, I had another idea that just came to me that may help further elaborate my point.
"person's legitimate property"
If you had a car, and that car was stolen from you then sold (on a free market) to another man. Does that last man "legitimately own it"? If you say that it is the last mans because he bought it. Then you're a capitalist (as I define it). If you say that it still belongs to you because the initial transaction was illegitimate. Then you probably agree with me (although you may not know it). Because capitalism is the original "original sin" where we stole things from every living being on the planet and all humans (who are and will be) and claimed individual ownership of it. That's where it all began! Ever since then it has been (if you agree with the latter) illegitimate transfers of property. The whole idea of private ownership (outside of personal ownership or homesteading) is illegitimate.
And this illegitimacy only stands through the use of violence (administered by the state, or feudal lords, or kings, etc)
This is a great question!
I think that the best answer is that as long as all three persons are still around and are identified, then the car must be returned to its original owner. Furthermore, the person who stole the car must also pay damages to the original owner. If the person who bought the stolen car did so in good faith (without any reason to believe that it had been stolen), then the thief must return the money plus damages to him as well. The fault lies entirely on the shoulders of the thief-fraudster.
The situation is different however if the original owner is no longer around or cannot be identified. Then there is nobody to return it to. Similarly, if the thief-fraudster is not identified. And if whoever has it now bought it in good faith, then taking it away from that person now is unjust.
You realize that in order for all these events to happen a state would have to enforce it. (or in the libertarian example a privately owned organization that somehow is given the authorization to administer force) through some random code of ethics (laws) that people abide by...
Not that this matters. I see now that there are some areas where we disagree. I would call that car stolen regardless if the person it was stolen from is alive.
Many would be grand-theft auto/murders would be relieved to know all they have to do is kill the guy who owned the car in order for them to sell it without it being illegitimate.
Of course, a stolen car is a stolen car. And stealing it in the first place was unjust. If we can correct this injustice by having the thief return the car to its original owner and return the money to the good faith buyer, then all is well. But sadly it is not possible to correct all past injustices without adding further injustice. Two wrongs don't make a right.
What alternative would you suggest?
Transitioning into collaborative ownership (which would benefit all people involved) it would be a non-violent means of doing so as people would voluntarily do this based on the benefits.
Then maybe there is a future where these terms of 'ownership' would no longer serve us. I'm speaking philosophically with my ethics (the future I see) I realize this isn't done in one step. It's a process. So, collaborative ownership of all private property (i.e. commons) would be my alternative, thus removing any sole private ownership. The car example is poor, I'm referring to the commons where a vehicle would be personal (with added taxes from Commons used resources, but that is another topic.)
As long as it would be on a voluntary basis, I have no problem with communities trying this idea out. No doubt, in a free world, where all human interaction is voluntary, different groups of people will live different kinds of lives with different rules and practices. It is an empirical question which rules of ownership benefits people the most, and I support the practical experimentation with different rules.
However, my prediction is that even though collaborative ownership might work in small enough groups, it will break down when groups grow bigger.
This is exactly the future I hope to help create. One where there is as diverse a system of relating as there are people to relate! That each one is tailored to it's participants! This is possible, and practical!
That's just it, with decentralized governance models they don't have to grow bigger! We can fractal this model on any growth scale and the division of collaborative ownership will never exceed roughly 150 people before it fractals out. As roughly 150 is what has been called an optimal number of people to interrelate. It's about as many people as we can recall names, information, relationships about.
