Sibling comments have given examples here, but the one-sentence summary would be that libertarians are in general opposed to licensure, and believe that a free market with certification (which would be provided by trusted private entities) is superior. In more detail, the argument goes something like "any time you require a license, you are necessarily reducing the choices available in the free market, and more choices are good." See e.g. Milton Friedman, "Capitalism and Freedom". I think the purist libertarian position on the FDA would be that it should be abolished and replaced with a private certification agency. But if you _must_ fund it with government money, it should be a certification body and not a licensing body.
