Why aren't there more libertarians?

Because people prefer identifying with winners. Libertarians don't win elections; they lack visibility and are maligned by both major parties, so few people actually want to say, "yeah, I'm a libertarian." At most, you'll get people who say they vote for X or Y party, but lean libertarian. For example, I consider myself a libertarian, perhaps more correctly a classical liberal, philosophically, but I don't vote for the Libertarian party due to policy and ideological differences.

What I've found is that most people can agree on generalities - we like freedom, peace, prosperity. Where we differ is in the definitions and practical implications of those words. People are too attached to single issues. They get hung up over things like abortions, gun control, and gay marriage, and disregard the bigger issues.

The vast majority of so-called libertarians in fact support capitalism, a social system that denies liberty to 99 percent of the population. You aren't free if you are subordinate to an employer and the impersonal market system.

True advocates of liberty want a classless stateless society where the planet's resources belong to everyone. No rulers, no billionaires. But not many people have seen few the pro-capitalist propaganda that surrounds us.

There are more and more libertarians out there it just seems as though they don't want to come out of the closet because they have not been winning elections lately but they have become more popular.

Because of the way libertarians "come across" when you talk to one of them. I consider myself libertarian in the sense they follow the constitution. But whenever I talk to a libertarian, other than Ron Paul, I find myself in disagreement with many of their beliefs. Example, gay marriage. I'm against it, they are for it. When I watch the show "the independents", they come across as silly snobs to me. Most libertarians (other than Ron Paul) talk and act like the people on that show "the independents".

I'm a left libertarian

It has to do with their imaginary system of rulership not actually being practical in the real world.

Most people realize that there are real world problems not covered by voluntary contributions and funding the military.

isn't libertarian just a fancy name for anarchist?

theres plenty of them about.

Because most people are either ignorant or desire control over other peoples lives.

They tend to die young, of smoking related diseases, cirrhosis of the liver, etc.

inbreeding has limited their existence.
