Aye. You won’t find many people who self describe as libertarians because it’s a very broad term - it can be applied to either or both of the economic and social spectrums and mixed with other ideologies to varying effect and so different terms tend to be used to explain where they lie on those spectrums.
The Orange book strand of the Lib Dems (Clegg, Laws et all) and Farage could both be described quite rightly as libertarians, but they have very different ideas about what their ideal society looks like.
