The problem with Gerson’s framing here is obvious: in what way is appropriate governmental action to achieve a public good determined? If we are in an era when social institutions are in decline – partially due to government, but due as much to culture – what limits if any should expansionists recognize on the size and scope of government? This is the equivalent of the general welfare clause: If there is any limit to what can be defined as a public good, which of Michael Bloomberg’s policies would Gerson describe as unconservative? Isn’t it good for people to be healthier, even if the state is being a bit of a nanny? Were local and private institutions really dealing with those problems of too much soda and salt?
