You are correct that there are cases where the nuances make it impossible to have one be "superior" to another, and I'm not arguing otherwise.

That does not mean that some systems can't be objectively worse than a collection of others. I also never brought up costs - healthcare outcomes matter, because...health.

I never made it a quest for superiority - I insisted that everyone participating in a discussion should be in a place where they CAN be convinced of some points - arguing from a place of facts, not unshakeable emotion.

To do otherwise is unhealthy for discussion.
