Stunned silence.
Why stunned? The example would be one of public drunkenness. Do we have a right to stagger around drunk in public? Well, it could be so-argued (and you could probably find a FR libertarian to argue it). But in reality it doesn't seem to violate anybody's legal rights if drunks are instead taken to the tank for the night.
It's a little disconcerting to think about, but the only behaviors local and state government can't ban are things that are constitutionally-protected (whether US constitution or the state constitution). Everything else is fair game.
I can't think of any argument that can support the proposition that you have a right to smoke.
