I think the quote isn't referring to somebody having a direct impact on you, but rather that you have to put up with their immoral behavior (in your view). In a free society a religious fundamentalist has to tolerate atheists.

Drunk driving and public drunkenness laws are mostly practical. They are a restriction on people's freedom before they've harmed other. The laws are preventative in nature and exist to preempt harm that reckless behavior could cause. They're not good for modeling the principles of a free society on, because you'd quickly arrive at a paternalistic surveillance state. The laws are a compromise between safety and freedom.
