Nope, a degeneration into politics would be marked by one or the other of us switching to "arguments are soldiers". I don't think we have.

I'll put my cards on the table here. I have a lot of respect for libertarian abstract pure capitalism. Its particular advantages that I don't think are equaled elsewhere are: a local update rule (making it embarrassingly parallel), by agents who are self-motivated (without external force) by monotonically increasing expected utility, producing coordinated activity without coordinated preferences, and typically producing compounding reinvestment that grows the technological and wealth base for everyone. I think capitalism is the fixed-point an economy will fall into if you have scarcity, enforce property, and don't do much else. It's the only system that can operate in the presence of scarcity without needing coercion.

I just don't necessarily think those advantages mean it's nice.
