Even speaking as an agorist, your faith in the market is a little extreme. It certainly has some useful and beneficial efficiencies to be sure, but believing that it will simply elevate the best and create a rising tide that will raise all standards is a little naive I think with regards to what we see in the world where markets reign.
Assuming humans are perfectly rational agents with equal information it works, but that's not how humans really are. Humans are dumb, panicky, emotional animals, and the difference between the most incompetent of them and say cows are not as wide as our politically correct institutions would like to force us to believe.
You would do well, even in an ancap society, to voluntarily donate to charities that pursued socially beneficial objectives so that you reaped the benefits of their actions. This is pretty much the ancap response to tragedy of the commons. Vaccination and libraries are not a bad example of where this makes sense imho. There's nothing strictly contrary to ancap doctrine to point out that choosing not to clean your proverbial home will result in you living in a mess, so you might want to do that occasionally.
It is not enough to point out that simply because states provably fail, markets are perfectly efficient.
Political discussion has, for a long time, been discouraged on HN. Down-voting is one way to encourage people to stop.
Also you'd be pretty hard pressed to say that this question isn't expressly relevant to the original article being discussed, and isn't overtly political in the sense that noone is agitating for votes or any such thing.
"Do buyers and sellers go to this man the way people go to real estate agents for their services? What would Craigslist buyers and sellers think of what he does if they knew about it? Respectfully, I think they would strongly prefer he weren't interfering."
"I doubt very much that sellers would appreciate this liquidity 'service' if it were spelled out for them. They would feel cheated, as would the buyers."
Pretty outrageous, in retrospect.
