I don’t think you quite understand what this argument is about. People who are not libertarians and opposed to their views are frequently not opposed to free markets, for example.
For example, I’m about as socialist as it gets, but I think free markets are an enormously powerful and efficient tools and that, in the grand scheme of things, they have been a huge net-win for the world. I just don’t think they are perfect and can solve every problem (better than alternative solutions could). That’s all.
Similar arguments apply to other things that are near and dear to libertarians’ hearts.

To me libertarianism is lazy extrapolating.
