Let's say that there is a hypothetical poison that makes food taste great. It's not a very strong poison, so it mostly doesn't kill anyone immediately, rather it takes repeated doses over a period of time before it kills. Let's say restaurants use it regularly to flavor the food. The poison is slow enough acting so that no one ever dies while still in the restaurant.
Let's also say that the effects of this poison aren't widely known: the patrons of restaurants don't know that the restaurant is using this poison and aren't even really aware that this substance is a poison; the restaurants and the employees don't really know that this substance is a poison either, just that it tastes good.
Finally, let's say that it's difficult to disseminate information about this poison throughout society because of naturally occuring constraints on communication of this sort (which I won't describe in this post).
Would a libertarian support any government action to try and stop the poisoning of the populace? An example of a possible action might include banning the use of the poison. There are other possible actions as well. However, assume that education of the populace (another possible government action) would take many years.
