Hey, no paranoid conspiracy intended. Simply thinking out the counterfactuals. Is tying a particular activity to "national interest" itself a form of paranoia?

Hey, no paranoid conspiracy intended. Simply thinking out the counterfactuals. Is tying a particular activity to "national interest" itself a form of paranoia? What about passenger aircraft is a strategic interest? For example, the US seems to do ok with little large-scale shipbuilding outside military concerns. People seem to take cruises from the US in ever-larger cruise ships without a domestic capacity for building them. Additionally, no disagreement on my part regarding the high regard people have for hypothetical rail. On the other hand, I'm open to the idea that high capacity terrestrial transportation similar to rail would have cause to improve if airplanes weren't in an optimization sweet spot.
