Authority

It occurred to me only recently (I can be quite dim) the reason that conservatives worship the free market.  Conservatives love authority--authority of all types.  The ultimate authority is God, of course.  The thing that the free market has in common with God is its unpredictability.  Yes, there is a near-science of economics, but try as it may to make predictions, it's far from perfect (particularly imperfect when ideology gets in the way of honest research, but that's a topic for another time).

Conservatives resist the idea that humans can have any significant effect on the world.  Part of the denial of climate change (apart from the greed that helps drive it) comes from conservatives' denial that climate change could be either caused or mitigated by human efforts.  God wouldn't let that happen.  The twin authorities of the free market right wing church know better than science.

Of course, part of belief in the free market comes from the sense of justice of the rich, who believe that it must be God's will that the both rich and poor are where they belong.

As they've done since the beginning, do now, and ever shall do, the benighted lovers of imposed authority fight against the erosion of that authority.  I used to separate the right from the left by describing the right as "the punitives."  They love doling out punishment, but now I think they love receiving it, too.
