Much too simplistic. Though if approached properly the concept is reasonable.
Assuming it isn't the only or the highest priority action taken, I think leaders, usually government but maybe the education system, have to have the expectation people need to change from these kind of archaic beliefs if they are to live in contact with the modern world. And the people in the news article fit that description.
But there are some tricky areas here that a lot of anthropologists would argue with that approach. Do you try to change the beliefs of the Yanomamo in Brazil? What about the tribal people in Africa who still live in isolation at least as far as roads go, and still live as they did 1,000 years ago with very little change? Do you just try to stop them burning witches or do you outlaw female genital mutilation? Do you try to stop them from ritual stretching of necks, lips, and ritual scarring?
It's time for the rural people who now live in a Johannesburg suburb to grow up. They don't have much claim to a traditional way of life one is destroying. But from there it is unclear how far to go, which beliefs to elicit change, and how to do it.
I think we can safely say converting them to Christianity is just as bad but look at the Evangelical recruitment going on in Africa and just about every other country in the world. Madrassas are springing up everywhere across SE Asia to Northern Africa. Muslim leaders, while using different tactics than Evangelicals are just as actively recruiting converts.
Depending on how you measure harm, WWIII, murder resulting from superstition, or a polio epidemic resulting from vaccine myths, the negative outcomes are clearly present in many false beliefs.
