Public vs private question

So, I will be fully honest with you, I’m not a libertarian and I truly only know what I thought were the basic tenements of what it meant to be a libertarian. But then a friend’s father me this comment and it got me bet confused as I thought one of the biggest components of libertarianism is to remove anything public. Could someone please enlighten me? Thanks!
