"I've never thought of the market as a god, never worshipped capitalism, and always understood the trade-offs any economic system presents to those who participate in it."
You are absolutely correct; too many in our movement have a Walter Williams-like reglious belief in unrestrained capitalism, that the market is ALWAYS right, and that the "law" of supply and demand was handed down along with the 10 Commandments!
I think you may be exaggerating a bit. The only people who would come close to that description are anarcho-capitalists, who make up only a small portion of libertarians. Among conservatives in general, they make up a tiny fraction. I'm sure we could name a few on this site, but that would probably be because their rarity makes them stick out in our minds.
Most conservatives/libertarians believe in SOME role for the state and some activities that should remain outside of the market; the building of roads, national defense, the establishment of courts of law, legilative bodies, etc. Furthermore, most recognize the need for certain restraints on market activities, like prohibiting fraud or imposing fines or restrictions on pollution output. And I think most can point to certain market outcomes we don't like. I, for instance, find the branding phenomenon in clothing to be repulsive.
There are very, very few on our side who believe in an unrestrained, infallible market. There ARE quite a few (thankfully) who recognize that correcting the faults of the market is quite often worse than the problems being addressed. Some of us defend the market not for what it makes, but for what is required to make it work- individual rights.
