> sure, greed drives efficiency in capitalism, but if it isn't reined in via regulation we wind up with the abomination we have today.

This is exactly where we part ways though. You specifically said "laissez-faire", i.e. "leave it alone" in French; economically this is anti-interventionist, let the markets sort themselves out without interference from government. You are saying regulation is required for the market to function or it leads to what we have today and I'm pointing out that we already have enormous quantities of regulation in healthcare. I pointed out several very easy examples to identify with but by no means is that an exhaustive list of healthcare interventions. The very thing you are advocating for, regulations, has been increasingly attempting to "fix" this market for the past 80 years and our current system exists because of it, not in spite of it. It is not a free market in any sense of the word, and doubling down on more regulation will not improve it. I am more than happy to debate an actual free market or nationalized healthcare model, but further regulating this "free" market is misdiagnosing the system we currently have and assumes the same good intentions that have failed to improve it for four generations will somehow produce better results this time.
