Sure, but Libertarians are also the one political ideology that the Communists can legitimately look down on, since hey, at least Communism has been attempted in the real world.
When someone says "I'm a Libertarian," what they actually mean is "I have no serious political convictions beyond Utopian visions of a world where people are something other than people." And that's fine...lots of people don't like real politics, and it's easy to see why. It's full of real people with real problems, and everything gets complicated fast.
Personally, I have no moral qualms with government involvement in the economy, because the economy is not a moral actor. Obviously, government involvement can be harmful in a number of ways, and so we want to be careful about using that tool. But not only is the tool available, it MUST be used from time to time, because capitalism, while powerful, is an ultimately unstable system that will fall over from getting too top-heavy if the government doesn't step in from time to time.
