The point is the customer wants security but he doesn't want to pay for it. So we give them an illusion of security instead, it's much cheaper. All a private company would do is tell a better lie for less money.
Except for the fact that security does not have to be perfect for it to be effective. No fixed defense is ever completely effective against a determined enemy because the attacker is the one in control of the circumstances of the attack. It does, however, prevent casual and even fairly determined but poorly-planned or resourced attacks from occuring; in most of those cases simply by making them appear infeasiable before they're even conducted.
Obviously security cannot be perfect. For one thing people make mistakes (from which we learn), and like I said, the attacker has the initiative.
The main flaw in the thinking that I'm seeing here though, si that terrorists generally get what they want from terror campaigns. Terror attacks tend to create outrage as much or more than fear. They don't usually cause people to cower in their homes afraid of their own shadows. If they did, Iraq would have starved to death by now. People demand action. That action may or may not be favorable to the terrorists.
Really, if terrorism were so easy and effective the entire world would have collapsed in the face of relentless terror attacks by now. Terrorism is not that effective because terrorists are not any more clever, brave, or efficient than anyone else, and because they make the mistake of pretty much any idealogue over the last century or so: They think ideological purity and resolve are what's needed to succeed. Those may give you motivation, but they can't replace resources or planning, nor does it account for the fact that one's opponents may not be all that impressed with your ideological purity.
However, just because security is not perfect does not make the existing security an illusion. It's not. It makes it much more difficult to carry out terror attacks than it otherwise would be, and every time one does succeed, lessons are learned.
