I have yet to see a libertarian candidate for local office. I do think that government should be stronger on the local level than it is now, and with no candidates who support what I believe, it is difficult to find a rational reason to vote. However, yes, libertarians, as it is a government-based system, would need to vote.
However, I only recently became a libertarian, so.
And yes, there is always the trouble of government overstepping it's bounds, as there is with
all governments. However, I don't see a situation arising (realistically) where government can be abandoned totally. Even if Galt's Gulch were to come into being, there will always be the irrational on the outside who need no reason besides greed to attack.
In a perfect libertarian system, there would be no need for force against rational people. The only time that force would be used is against irrational people who instigate the force and refuse to answer to rational thought.
From the Ayn Rand website:
"In a free society the government uses force only in retaliation, against those who start its use. This involves three main functions: the police; the military; and the courts (which provide the means of resolving disputes peacefully, according to objective rules)."

Of course, the issue of taxes does raise some troubles. I suppose it would be possible to refuse to pay taxes, and willingly give up services in return. A fee required for calling police, asking courts to deliberate disputes, etc.
