What? It is insane for a person to have to pay for TB treatment. We have a huge TB burden here in South Africa. Treatment is free because we don't want it to spread. Unfortunately, because of the massive urbanization movement after Apartheid, the shanty towns makes the spread quite easy.

It's insane for you. For them, it's good business sense, because they can protect themselves from respiratory disease. Even better if you can sell orphan drugs for huge markups because TB requires specialty antibiotics. Follow the money, as they say...
