Actually, reducing irrational fear of terrorism can reduce incidence of terrorism - as terrorism becomes a less effective tool it will be employed less. "Refuse to be terrorized" isn't a bad meme.
Beyond that, one doesn't need to fear the first-order effects of terrorism in order to support such a program. Fearing damage done by undirected (or maliciously directed) overreaction to terrorism is plenty.
"This also would only ever be a private effort, as it would completely undermine the goals of the state."
I'm not convinced the state is quite that monolithic, but I think this is likely better as a private effort anyway.
