From this Conor Friedersdorf piece in The Atlantic:
I do think that, if libertarians had wielded more power in bygone years, America would not have passed the Patriot Act, started the phone dragnet, or allowed the Department of Defense to send military equipment to police in places like Ferguson, Missouri.
On issues where libertarians have a somewhat realistic chance of winning over their fellow citizens—reining in the NSA, eliminating the most inane professional licensing laws, insisting on due process in the War on Terrorism, avoiding foolish wars of choice, ending the war on drugs, reducing the prison population and the militarization of the police—a "libertarian moment" would have a salutary effect on American life. . . .
