"Choice, competition, reducing costs -- those are the things that I want to see accomplished in this health reform bill," President Obama told talk-show host Michael Smerconish last week.

Choice and competition would be good. They would indeed reduce costs. If only the president meant it. Or understood it.

In a free market, a business that is complacent about costs learns that its prices are too high when it sees lower-cost competitors winning over its customers. The market -- actually, the consumer -- holds businesses accountable and keeps them honest. No "public option" is needed.

So the hope for reducing medical costs indeed lies in competition and choice. Today competition is squelched by government regulation and privilege.

But Obama's so-called reforms would not create real competition and choice. They would prohibit it.

Competition is not a bunch of companies offering the same products and services in the same way. That sterile notion of competition assumes we already know all that there is to know.

But consumers often don't know what they want until it's offered, and their preferences and requirements change. Businesses don't know exactly what consumers want or the most efficient way to produce it until they are in the thick of the competitive hustle and bustle.

Nobel laureate F.A. Hayek taught that competition is a "discovery procedure." In other words, the "data" of supply and demand emerge only through the market process. We need open-ended competition not merely to see which rival is better, but to learn things we didn't know before and aren't likely to learn any other way.

"Competition is valuable only because, and so far as, its results are unpredictable and on the whole different from those which anyone has, or could have, deliberately aimed at," Hayek wrote.
