Airport security measures were excessive even before 9/11, and they have only gotten more so. I have yet to see a good argument for even the restrictiveness of preventing non-ticketed passengers from going out to the gate (e.g. to be with friends or loved ones until boarding time) which was prohibited sometime in the 1980s or 1990s, and the additional restrictions imposed in the wake of 9/11 are not only dehumanizing but also do not even address the (possibly valid) issue of preventing terrorism from taking place on airplanes.
I don't know that I would go so far as the libertarian suggestion that passengers be encouraged to bring personal weapons including guns, but it's certainly less absurd than many of the measures currently in place.
