Kelseyfrog is trolling and enjoys using straw-man arguments to poke fun at other ideologies. I've debated with them before. Have you ever seen an ancap with pronouns in their profile lol? It's sarcasm.
It seems like what people are trying to say is that market outcomes dictate market success. Eg: bad market outcomes = bad place to hold a market, but no one is flat out saying it. At the same time, we have the idea that markets are "the best thing we have and any limits on markets produce negative outcomes." This is a contradiction and at this point at this place, I don't think debating that topic directly is going to teach me anything. Debating the fringes, however is.
It's the same thing as saying "X doesn't work" on StackOverflow and getting people to prove that it does. It's that we're doing it with something non-tech this time.

The conversation flits around a bit too quickly for my taste, but some interesting points are made.
