Explaining why health insurance companies should compete

Posted here because I couldn’t do a good job explaining this at dinner last night: Why is competition between health insurance companies useful?

This is not the world we live in, but it is the world we should aim for and I am more than willing to consider how government might get us there.  (Mandating greater price transparency is but one step.)  But if we institute a single-payer system, or highly regulated mandates, we will never have much chance of arriving in that world.  Ever.  We will have a fairly static sector with high coverage levels but rising costs long term and less innovation.
