Or how about when making sure education reaches everyone's hands.
See, the funny thing about people defending libertarian positions is that if they hadn't lived in a country with a public education infrastructure, roads, fire brigade and energy, it would be very unlikely that they'd had the capacity to acquire the knowledge and stability they'd need to become what they are today.
The inescapable fact is that they did nothing to "deserve" their health care of education through their infancy, yet it's one of the core reasons they got here, and they have the gall to complain about it.
Evidenced by the high standards of living in countries which do have social infrastructure (and yes, it exists, no need to put quotes around it) it works, and works reasonably well.
Doing infrastructure planning and development for millions of people kicks in economies of scale which are unachievable otherwise. History has effectively shown that social benefits that guarantee a minimal level of rights for education and health have dramatic effects in social mobility and overall quality of life.
