Abstract: The article presents a response to comments by Daniel Klein published in the August 2004 issue of the "Econ Journal Watch" on the article "Libertarian Paternalism Is Not an Oxymoron," by Cass R. Sunstein and Richard Thaler. The author rebuts Klein's suggestion that the authors are making an idiosyncratic distinction between voluntary and coercive action and states that their distinction is the pivot of the argument that opposes libertarian paternalism to nonlibertarian varieties.
