All of us have experienced government road closures and the traffic and safety nightmares they create. Private roads may be the answer to solving the problem.
We've all been victims of the devastating question "Who will build the roads?" And of course we're all well aware that no libertarian thinker has ever addressed it.
Sarcasm aside, I think a much more interesting question than "Who will build the roads?" is "How do we transition to private roads?"
I've lived places that have considered private road solutions to congestion problems and skyrocketing infrastructure costs. Implementation is tricky, because the road network is very valuable, but on the margin each road may have many substitutes.
If you sell the entire road network at once, there will be issues of monopoly pricing that will piss everyone off. However, if you auction of individual roads, potential buyers might not be able to earn the revenue needed for maintenance and liability, because drivers will shift to the still free state owned roads.
There are many solutions to those problems, of course. How do you all think the existing road network should be dealt with?
