Which libertarians are you talking to? Every libertarian I've read or heard from has been against these "[t]emporary and mild authoritarian measures". The more popular libertarian publication/website, "Reason" has been against (all?) these measures.
Libertarians or libertarians? I know a half dozen people that are, what I consider, very libertarian (not Libertarian) personally that think its entirely reasonable.
Most Libertarians are extremist libertarians in my view.
