Certainly, I think we would be best served by the most broad and liberal definition that we could give to “public purpose”. If there was an agreed upon definition it would have to be that, anything that has a public element tied to it. For example, for ancillary health services like cleaning, is that for a public purpose or not? It serves the public, but you could argue that it isn't.
