Each of these systems is degrees of the other as well, and that seems proper for the exact reasons you mentioned - not including desired externalities in pricing/market dynamics.

There are a few things that I believe only work in a moral way when they are taken out of the hands of capitalist pursuit-of-profit dynamic:

* Healthcare: What does the demand curve look like when your alternative is death or a painful, limited life?

* Pollution/Environmental damage control: Without regulation the chemical company owner has zero incentive not to dump their leftovers in the creek.

* Access to quality education: Equality of opportunity

* Access to housing: Simply a question of morality. In the US at least, we have so much goddamn money and so much goddamn land and the ability to build giant buildings on that land. No one should be homeless.
