Uh, didn't we have the mandatory shoe removal for a while already after the shoe bomber? Shoe removal is still commonly demanded if the metal detector gets triggered and many places have special shoe scanning devices too.

And we still have the liquid ban, thanks to one plot that wasn't even realistic to start with.

So sadly "safety" and security theater where you get to show to your electorate that you are "doing something about it" will always win over inconvenience and common sense.
