Government does far too much, and should not involve itself in more matters than it has to. Alas for Andy’s point, one of the very few areas in which government does and should involve itself is public health. The promulgation of rules involving the management of disease — so that plagues do not break out routinely — and the proper disposition of diseased bodies and deceased corpses remain one of the linchpin purposes for which humans gather together in a society. You can certainly argue that the promotion of novel new ways to enhance public health like the use of stem cells is not the government’s business. But I fear very, very few people would agree with this notion these days, except for philosophical libertarians. We would be better off if more did, I guess, but that ship of limited governance has long since sailed.
