Why would they jump over the concept when it's the same companies providing the treatment? They would rather have repeat customers that will come back spending money for the rest of their lives than to cure them once for a fee using a relatively cheap treatment method and never have to see them again.
And what do you mean it's not about financial reasons? Everything is about the money. If you really think that these people would rather save lives than add to their already tremendous wealth then you're just being ignorant. And even if it's about the health of people, our world is on a quick path to overcrowding and running out of resources. Why would people stop a disease that solves this problem naturally?
Your missing the point that they don't give a fuck about your life or helping others, it is strictly about the money and furthering the existence of those elite few. One way to do this would be population reduction.
