It works pretty well if you strain the definitions of "initiate" and
"force" a bit. Most libertarians would consider not only self-defense,
but post-hoc retaliation (such as arrest, trial, jail, etc.) not an
initiation. And some conveniently redefine "force" to include things
like intellectual property violation or blackmail to justify laws
against those things. Most also include the threat of force or
reckless endangerment as "initiations of force" that one may defend
or retaliate against.
Complete LeFebvrian pacifists are a rare subset of libertarians.
