It turns out that having some regulations and laws in place makes for better living. Having sanitation codes prevents illness, and means your apartment isn't flooded by someone else's excrement. It also means the water you drink won't kill you and neither will the foods you eat. Regulations, it turns out, have a constructive use in our society. They make our lives better.
Libertarianism is a dead-end, politically. We already live in an age of deregulation where people can be "free" to squander their wealth and end up homeless and destitute. We have removed the safeguards from our financial system, and then look on in wonderment when it collapses all around us, when we resort our basest instincts of greed and fear.
In short, we are about two steps away from the Kowloon Walled City as it is. I am not sure we need to move any further toward this "utopia" of modern living.
