but the airports won't be threatened with closure if GA is
expanding and healthy.

Sure they will. The economic forces are the same - even a healthy GA
population at a small airport that is in a developmentally desirable
area will not make enough money to fend this off. Granted, healthy GA
contributes economically many other ways, but those ways are mostly
hidden and indirect, making airports still an easy target.

True, but we overlook the fact that a redeveloped airport site will still
generate indirect income. More than likely, a well developed airport site
will generate more indirect/hidden income in one week than what the airport
does in one year, including both direct and indirect income from the
airport. Arguing economics as a justification for a GA airport is usually a
losing argument once the facts are clear.
