I see it more as an interesting read than anything else, and enlightened me to one person's issues with libertarianism. Sort of like reading a novel with political viewpoints: you can agree with it or disagree with it. It doesn't have to "produce signal".
No, but a personal anecdote about libertarianism as a political ideology is the sort of thing that breeds argument, but no debate.
EDIT: So I went ahead and looked up "debate" in a dictionary and it apparently doesn't mean "principled argument", I'm not sure what the word for that is, but basically a post like this generates a lot of noise but produces little to no signal.
