>If sanitation is a "social problem" then everything is a social problem

Social = society, keep that in your head.

The vast majority of problems you are going to face in your life are social problems because you live in a vast interconnected society with millions/billions of other individuals.

And it is important to remember that almost all problems are social problems, we get a quite a few of the libertarian types on HN that think "I'll just ignore other people and now I've solved every problem in the world". It's why this group of people thinks this way, it makes the problem way easier if you ignore reality.

Money, and the assorted scams around it, regardless of what type of money it is, is a social problem by definition.

You see this a lot from people who have been lucky enough to live in places where problems get addressed somewhat automatically. When you spend enough time in places where that isn't true, you quickly realize how indoor plumbing - or almost anything, really - becomes a social problem.
