Not really. It only seems that way because most of us have only had experiences with the psychotic capitalist neo-libertarians of the Murray Rothbard school.

Actual libertarians, left libertarians. Can definitely get pretty squirrely when you get out on the fringes of ideologic anarchists etc. But many are fairly rational and even generally pro social democracy.

Right-wing libertarians are just an oxymoron. Under capitalism none of us can truly be free and we are all subject to the whims of wealth hoarding psychotic oligarch monkeys. They'll tell you that you're free not to work for them. The only problem is choosing not to work for them means choosing starvation, homelessness, and death. Which isn't the sort of thing that should be considered a choice in any civil society. But absolute necessities for unsustainable systems such as capitalism.
