The moloch reference is a shibboleth for the rationalist community. It’s not an actual religious reference. There’s another reference to “updating” further down which is another rationalist term meaning “updating your priors”.
All I was trying to say was that the organizing ideology of such a system (healthcare) doesn't matter as much as having enough people committed to and working within the system. A capitalist version may work better than a communist one, e.g. at developing new approaches to disease, or serving more people in more tailored ways, as long as the incentive structure exists to bring enough people into the workforce so that each practitioner is not overwhelmed.
TL;DR I was playing along with the "moloch" reference, although clearly it means different things to different people.
