Yes, you're missing the fact that you're making up the example to fail.

Look, nothing is perfect. Let's say you were shopping for a new car, but one had slightly uncomfortable seats, another had shitty stereo, the third had no cupholders and the fourth completely lacked trunk space. In that situation do you give up and walk everywhere complaining about having to walk?

More to the point, in reality the Libertarian party would do more of what you want than any other party. So all of you anarchists collectively, whose vote might not collectively be statistically insignificant decide not to vote and let the big government Republicans and Democrats win. You could vote in a Ron Paul or Gary Johnson who'd reduce the size of the government and get rid of laws against drugs and reduce taxes. It's not everything you want, but it's on the right path and if your ideas work out people would see life getting better and be more likely to stick to that path.

Instead you opt out until you can change everything instantly, and lose everything... then complain about it endlessly.
