I already replied to this thread, but as I reread your original post I saw some more things I wanted to comment on.
"No one mentioned this that I saw, but maybe a company would be paid for transporting criminals outside the borders of the anarchistic area."
Probably. I imagine that people who had refused to comply with the mandates of a DRO or similar orginization after commiting some kind of heinous act which left them incapable of coexisting in a peaceful society would be given the alternative of being transported out of that society to some place where their kind was welcome at their own expense. This may mean transfer to a penal or mining colony where high risk individuals were excepted because the need for labor outweighed the greater risk, or it could mean transfer to a state run society which allowed their immigration. If there was no such alternative, or if the offender could not afford it, then this service would probably not be offered. Of course, upon delivering the criminal to the new area, the transportation company would have some legal obligation to inform the inhabitants there of his history, which might make living in this new place problematic, but if they failed to do so, they could possibly face litigation themselves.
"How would a street owner make a profit off of owning a residential street? Who would pay for it? Would anyone who wanted to pass through the area have to pay a toll? Would the people who lived on the street pay for it and charge their houseguests a fee for visiting them? If someone's car broke down on the street would they have to pay a fee for the entire time it was left there awaiting repairs?"
In my last post I addressed at least to some degree the ownership and financial aspects of the roads. As to your question about vehicles breaking down in the roads, I imagine that a well run privately owned road would have a financial incentive to monitor their roads for this sort of thing, and get a tow or repair truck out to the disabled vehicle as quickly as possible at the vehicle owners expense. A stalled or disabled vehicle would block traffic and discourage people from taking that road to their destination, thereby costing the owner of the road money. Even with todays technology people with GPS systems can receive real time updates on traffic conditions along their route. Almost the instant a vehicle became an obstacle to traffic, the road's owner would begin losing money. It's even possible that some road owners would offer towing as a free service to entice more people to drive on their roads thereby increasing profits.
"I think that it would be too inefficient to have the avenues upon which things flow from high concentration to low concentration be a series of individually owned toll roads."
I think the problem here, and I may be wrong if so I apologize, is that you are envisioning a toll booth every time someone turned off one road onto another. With modern technology there would be no reason for there to be physical toll booths, in fact, it would not be an economical way to collect tolls. I addressed the issue of toll collection in my other post, but in short, I believe tolls could be tracked and collected electronically without any interference in the flow of traffic.
"Of course, this opens up the question of other things that, rather then being publicly owned, are simply not owned at all."
I think this is entirely possible. For instance, there would probably be areas of land that were unowned, at least temporarily. And it's certainly possible that the ownership of some items could lapse due to death or disuse. There would also be thoughts, ideas, and concepts which would defy singular ownership. And if we accept the possibility that in the future humanity will move beyond the confines of one planet, then we must accept an entirely unowned universe, at least unowned by humans. I think the important difference here is that under the current system, the state claims proprietary ownership of everyone and everything. They claim ownership over the land, the people, their rights and priviliges, their bodies, and the fruit of their labor, and this claim of ownership is upheld through force. Under a voluntary society, ownership is an individual right, created by labor and maintained through contract and use.
