Is the Libertarian Party the answer?

I, like the rest of you gets tired of the same old politics that comes out of the Republican and or democrat parties. But my question is this. Is the Libertarian party the answer?
Lets take a look at the Libertarian party then I will let you decide on your own.

On the National libertarian party website it states : “Libertarian: A person who upholds the principles of individual liberty especially of thought and action. Capitalized: a member of a political party advocating libertarian principles.
Libertarians believe in, and pursue, personal freedom while maintaining personal responsibility. The Libertarian Party itself serves a much larger pro-liberty community with the specific mission of electing Libertarians to public office.
Libertarians strongly oppose any government interfering in their personal, family and business decisions. Essentially, we believe all Americans should be free to live their lives and pursue their interests as they see fit as long as they do no harm to another.
In a nutshell, we are advocates for a smaller government, lower taxes and more freedom.
Libertarians are neither. Unlike liberals or conservatives, Libertarians advocate a high degree of both personal and economic liberty. For example, Libertarians advocate freedom in economic matters, so we're in favor of lowering taxes, slashing bureaucratic regulation of business, and charitable -- rather than government -- welfare. But Libertarians are also socially tolerant. We won't demand laws or restrictions on other people who we may not agree because of personal actions or lifestyles.
Think of us as a group of people with a "live and let live" mentality and a balanced checkbook.”

I only have a few question about the Libertarians. If the statement “Libertarians strongly oppose any government interfering in their personal, family and business decisions.”
Does this mean that one is free to do anything they want in their personal lives? Does this mean I have a right to do all the drugs I want? Should drugs of all types be legal. Should we set up a government agency for those who want to do this where they do not have to steal off you and me to support their habits?

Does this mean that we should not have any zoning laws? Its ok for me to put my twenty year old trailer on the lot next to your $200,000 house?
Family? What does this include? Is it ok with them if I have five wives and three husbands? Maybe throw in a couple of animals into this group.

“ Principled: The Libertarian way is a logically consistent approach to politics based on the moral principle of self-ownership. Each individual has the right to control his or her own body, action, speech, and property. Government's only role is to help individuals defend themselves from force and fraud.”

So by controlling one own body and action, you can do just about anything you want to do. Of course in a perfect world this might work but as we all know that there will always be those in a society like ours that will be standing at the door to take advantage of you at any cost.
So I ask, What is the libertarian really about. You can read more at:
