One answer might be that culture, an exclusive, frivolous, leisure pursuit of the rich, their flunkies, and social climbers, requires elaborate security to defend its providers and consumers from the righteous anger of the people, whose hard-earned taxes, or lottery losses, are squandered on subsidising fripperies such as opera, ballet, theatre, concerts, and art shows with dead cows in aspic, to which la-di-dah people wear fancy clothes. Another, from the opposite side of the social divide, might say that cultural performances and artefacts embody the best in the spirit of the nation, thus belong to all the people, irrespective of who owns or attends them, and are a source of pride and prestige for all, which must be defended against attack by foreigners, terrorists, hooligans, and madmen. The former is the view of philistines, the latter that of culture vultures.
