Calling it an illusion implies that air travel is not safe, when in fact it is very safe. However, people did not feel safe, so the government constructed an agency (perhaps deliberately, perhaps not) to provide security theater and help people feel safe.
In general, American citizens today are safe from terrorism. If anything, the greatest danger comes not from terrorists themselves but from the American peoples' unjustified fear of terrorism. We could use some more security theater.
This is either sarcasm, or, the most perverse and backwards logic for government sanctioned security programs that I've ever seen.
The ostensible reason that the government has created the TSA and its ilk is for actual security. Claiming that it's been created to intentionally achieve security theater is quite a extraordinary claim to be making. Furthermore, the origin of danger does not come along a single axis running between "terrorism" and "people's fear of terrorism". The government programs themselves can have negative impacts (c.f. any discussion on the TSA, NSA, border controls), which you are conveniently ignoring.
Firstly, I said "perhaps deliberately, perhaps not" because I am not claiming that they intentionally wanted to provide security theater. I don't think that motive is relevant. I'm replying to a specific statement to explain that there is a benefit, even though it is intangible. Of course there are other bad effects, like inconvenience to travellers, and other good effects, like providing stable jobs to otherwise unemployably stupid Americans who live in or near airport-bearing cities.
In retrospect, I should have mentioned that last bit instead as a tangible benefit, but I only just now thought of it.
