Oh, yeah, you're right that the present paradigm has outlived its usefulness, for sure.

But like any technology, not everybody has access to the latest developments.

It's unfortunate, but nevertheless true, that there are many places on earth where people have no other means of social support than the meager and dubious amenities provided by religious orders.

I'm sure there are those who might successfully litigate the argument that having no hospital at all could be construed as somehow better than having a hospital founded via religious means, and the imperialistic, colonizing aspects of missionary work, which directly damage cultures and societies on a generational scale, may indeed have caused more harm than the acute disease and occurrences of injury which they can treat on an individual basis - but that's not an argument I would personally back.

The corrupting mimetic contagion of religiosity can be inoculated-against while a society continues to benefit from the medical or nutritional support... although only if the society in question either learns how on its own, or is taught. Like most things in life, not quite so simply cut-and-dried, alas.
