Intrusive: Depends on how sensitive you are about stuff like this. They're only going to be screening flights from the worst hit West African countries. It's a temperature check before you get on the flight, and another one after. We've had way more intrusive security measures in place for EVERY person flying in the past (and present).

Expensive: More expensive than not doing it, sure. There's only about ~150 people entering the U.S. daily from the Liberia+Sierra Leone+Guinea. The screens will be performed using digital thermometers. The cost should be relatively low.

Demonstrably Irrational: It's not really irrational to take the potential for public hysteria surrounding this issue very seriously. If people believe that we're just letting at-risk people travel freely between W. Africa and the United States then things are going to get very nasty the moment Patient 1 shows up (P0 died a few days ago). CDC (Frieden) admits that the checks might make people feel safer but the real focus needs to be on containment in Africa. Everything else is going to be a half measure by comparison.
