Erm, there's a sort of gradient with free market on one end and government control on the other. "Injecting government control" puts you at a different level on that gradient than you would be in a purely free market.

"Conservatives" don't hold a monopoly on using a market. In most cases, they're not even completely in the "free market" portion of the gradient.

Please stop with the partisan labels. They're really not all that helpful.
